UPDATE: Sources confirm that Valentino Rossi was not at Yamaha HQ, and the news of his appearance was a hoax caused by a hacked Twitter account.

Valentino Rossi is set to make a return to Yamaha, abandoning Ducati after two long and difficult years of failure. The Italian was spotted at Yamaha Motor Europe’s headquarters at Schiphol-Rijk, an industrial estate next to Amsterdam’s Schiphol airport, by former racer Niall Mackenzie, who was visiting the Yamaha HQ while negotiating a deal for his younger son Tarran to race in Superstock next season. The Scotsman posted the sighting – naming only a ‘well-known Italian’ wearing ‘a big smile on his face’ - on his Twitter page, but when contacted by Thomas Baujard of the French magazine Moto Journal, confirmed his report to the magazine.

The news of Rossi’s return to Yamaha has been slowly leaking out since last Sunday’s Red Bull US Grand Prix at Laguna Seca. Speculative reports have appeared in leading English and Italian media, with Italian sports daily La Gazzetta dello Sport reporting that Rossi has been offered a two-year deal with Yamaha in MotoGP, with the option of making a switch to World Superbikes, to lead the development of the all-new Yamaha YZF-R1 which is expected for 2015. Yamaha pulled out of the World Superbike series at the end of the 2010 season, citing the global financial crisis and failing to achieve their marketing goals with the production-based series.

Just one more week, and the biggest open piece of MotoGP’s puzzle should be slotted into place. On Saturday night, Valentino Rossi met with Ducati CEO Gabriele Del Torchio, to discuss the details of the offer Ducati have for Rossi, and on Sunday morning, Del Torchio told French journalist Michel Turco that he expected to know Rossi’s answer within the next seven days. The money from Ducati is generous, some 17 million euros a season (this figure has since been denied by Rossi — Ed.), if the rumors are to be believed, but the money will not be the important part of the deal.

The biggest item will be what help Ducati will get from Audi, and whether the rate of progress at Borgo Panigale can be ramped up to start rolling out updates faster, and start to change some of the things which Rossi and Burgess believe are vital before the bike can even begin to become competitive. Ducati is not Rossi’s only option, of course.

The second seat at the Factory Yamaha team awaits, though that ride is not so richly rewarded, financially at least. The offer from Yamaha is rumored to be around the 3-4 million euro mark, a pay cut Rossi may be willing to take if it leaves him capable of winning and challenging for championships again. But here, too, conditions will be key: Rossi will return as the #2 rider, Lorenzo already having clinched a two-year deal with the factory, and Yamaha having made it clear to Rossi that they saw Lorenzo as the future back in 2010, which caused Rossi to pick-up sticks and go to Ducati.

Even worse, though, Rossi may have to return alone; his crew will not automatically be rehired by Yamaha, the cost of flying them around the world being a major cost factor in the equation. What’s more, Rossi will have to bring sponsorship to the table, much more than just the amount needed to cover his salary.

Confirming what we already reported yesterday, Ducati Corse has officially made it official that Nicky Hayden will officially be riding in the official factory Ducati team next season, officially. His tenth season in MotoGP, and his fourth with Ducati, Hayden has re-signed for another one-year stint with the Bologna brand. An important figure for Ducati’s North America efforts, Ducati Corse heavily mentions Hayden’s influence on American owners as its reason for retaining the Kentucky Kid in its press release.

Generally said to be the hardest working rider in the MotoGP paddock, Hayden not only is a workhorse for the Ducati Corse team, as it tries to bring the GP12 and its progeny into the competitive fold, but Hayden is also an active figure for his and the team’s sponsors. With that sort of work ethic and only eight points separating him in the Championship from teammate Valentino Rossi, Hayden’s re-signing seemed like an obvious choice, though Ducati is said to have offered the American’s seat to Cal Crutchlow earlier this season.

Making the rounds in the MotoGP paddock today at Laguna Seca, several sources close to the matter revealed to Asphalt & Rubber that Nicky Hayden is to announce a contract extension with Ducati Corse for the 2013 season this race-weekend. Pegged to be a one-year renewal, Hayden’s place at Ducati has been in a precarious position, ever since it was revealed that Cal Crutchlow had received an offer from the Italian team.

A workhorse for the Ducati, in addition to his personal sponsors, Hayden has been an integral member of the Italian brand ever since he joined the team back in 2009. With the United States now Ducati’s most important market in terms of sales, having an American on the company’s MotoGP team has been an important consideration for Ducati Corse, and the re-signing of Hayden to the Ducati Corse squad bodes well that Bologna has finalized its 2013 plans as well.

In a surprise announcement ahead of the US GP at Laguna Seca, Ben Spies has announced that he intends to leave Yamaha at the end of the 2012 MotoGP Championship season. Revealing the news in an email to Superbikeplanet, Spies chose his words carefully, though the Texan hints at a rift between himself and the Yamaha Racing MotoGP team as being part of the reason for his departure.

Certain to be bombarded with questions during Thursday’s pre-race media scrums, Spies is likely to shed more light on the actual situation, and his plans for the future, at the start of the Laguna Seca round. Until then, read his statement after the jump, and let the conjecture, double-reading, and wishful thinking begin.

World Superbike in Brno this race-weekend, the home round for the Czech-based Effenbert-Liberty Ducati team. Once again in the spotlight after its dust-up following the Monza round, Effenbert Liberty rider Sylvain Guintoli took to Twitter ahead of WSBK’s stop in Brno, announcing in a string of messages that that Czech team had breached its contract with him by not providing a bike for the Czech round, and as far as the French rider was concerned, the contract had been nullified.

Giving its side of the situation several days later, Liberty Racing first cited an issue with Guintoli’s technical team, but later amended that statement by blaming Guintoli’s lackluster results as the reason for why the French rider had been sacked. This is of course in spite of the fact that Guintoli has been on the podium three times this season so far, including a race win in Holland. Guintoli is currently eighth overall in the Championship, and is the first Liberty Racing rider to have won a race in WSBK.

HRC has today confirmed the news that has been expected for several weeks now. Dani Pedrosa and Marc Marquez have both signed up to race in the Repsol Honda team for the next two seasons, 2013 and 2014. Both riders are long-time protégés of the Spanish petroleum giant Repsol, so the combination of Marquez and Pedrosa in the factory team was the logical choice.

Once the Rookie Rule had been removed – at the request of the Honda satellite teams, for whom Marquez would have caused problems with crew members and sponsors – Marquez’s move into the factory Honda team was inevitable. As for Pedrosa, the Spaniard has consistently won races every season he has been in MotoGP, and has been in the title race most seasons, though injuries have prevented him from mounting a serious challenge.

At Mugello, a large number of pieces in MotoGP’s Silly Season are expected to fall into place. The long-expected announcement of the Repsol Honda team will be made on Thursday, according to Catalunya Radio, with Marc Marquez taking his place alongside Dani Pedrosa, who has inked a two-year extension with HRC. Pedrosa acknowledged at the Sachsenring that there were only details left to clear up, and after winning Germany, the Spaniard appears to have cleared the final hurdles to a new deal.

Mugello also looks like being the deadline for Cal Crutchlow. The 26-year-old Coventry man has offers of two-year deals from both the Ducati Corse team and his current Monster Tech 3 Yamaha team. What Crutchlow would really like is a seat at the factory Yamaha team, but with that seat probably unavailable – either being held open for a possible return to the fold of Valentino Rossi, or else retaining current rider Ben Spies – Crutchlow is instead likely to accept Ducati’s offer of a factory ride, believing that factory equipment is his only chance of winning races and a Championship. According to British motorcycling journal MCN, Crutchlow has been given until Mugello to make up his mind.

The German round of MotoGP is to stay at the Sachsenring circuit until 2016. Dorna announced today that they had signed a five-year deal with the ADAC, who own the Sachsenring, to keep the race at the circuit. The race had been under threat earlier, after projected losses for the German GP meant that circuit feared not being able to afford the event.

Dropping a bit of a bombshell ahead of the British GP at Silverstone, Yamaha has announced that it has retained the services of one Mr. Jorge Lorenzo for the 2013 and 2014 MotoGP Championship seasons. Coming to Yamaha in 2008, Lorenzo won the Rookie of the Year title that year as he finished the Championship in fourth place. Second in 2009, and winning the Championship in 2010, Lorenzo was runner-up again last year, and currently leads the Championship by 20 points (his worst finishes this season thus far have been his two second step podiums) — all in all, not a bad legacy to continue with the tuning-fork brand.

A major piece in the 2012 Silly Season puzzle, Lorenzo’s steadfastness with Yamaha Racing means that a seat remains open at Repsol Honda garage (likely to be occupied by Marc Marquez, as the Rookie Rules seems set to be abolished this year). The move also means that there will only be one seat to be fought over in the factory Yamaha squad, with Ben Spies, Cal Crutchlow, and Andrea Dovizioso all having an equal claim to occupying it.
