Despite the typically variable and sometimes awful weather all week at Phillip Island, the clouds seemed to understand that Sunday afternoon was to be Casey Stoner’s last race at the Australian track, and obliged the jam-packed Aussie crowd with warm rays of sunshine.

On form all week, despite his ankle injury, Stoner was a landslide favorite to win the Australian GP, and the 53,100 fans in attendance were treated to one more showing of Stoner’s unique understanding of the Phillip Island race circuit, which now has a corner bearing his name.

With Casey doing what he does best at PI, the attention as the race started was as to whether a second World Champion would be crowned this Sunday, as Marc Márquez had locked up the 2012 Moto2 World Championship just a few minutes before the MotoGP race. With Lorenzo needing to beat Pedrosa to claim his crown, the Australian GP got underway in earnest.

One of the three “flyaway” races before the season finale in Valencia, the Japanese GP is race that is not only important to the two remaining Japanese manufacturers in the premier class, but it begins the dénouement of the MotoGP Championship.

Finding renewed vigor in his Championship hunt, Dani Pedrosa has only a handful of races left to catch Jorge Lorenzo, and win his first premier-class title. Truthfully needing Lorenzo to make a critical mistake or suffer a mechanical failure, Pedrosa also has to keep the pressure on his rival, and try to minimize the gap to his fellow Spaniard.

With each place separating the two riders likely to play a pivotal role at the end of the season, the drama unfolding in Motegi was palpable, though the action itself was a slow grind of a multi-campaign war.

After two days of miserable weather at Aragon, race day dawned dry, sunny, though still a little cool. Paddock regulars who had spent the last two days scurrying from pits to hospitality, seeking shelter from the rain, poured out into the paddock to catch the warmth of the sun, which they had just about given up on previously.

The blue skies brought out some great racing, at least in Moto3 and Moto2, as well as some fantastic displays of riding in MotoGP, though the excitement in the premier class was to be found in the battle for the final spot on the podium rather than in the fight for victory. But there were also a few signs of improvement in the near future.

If you were writing a script for a blockbuster movie based on MotoGP, you would be off to a great start with a premise centered on Tech 3′s current riders: Cal Crutchlow and Andrea Dovizioso. This current season would be the backstory, perhaps told in flashbacks or in a montage behind the opening titles. Next season is where the drama would unfold in earnest, as each character pursues a World Championship on a different team.

But perhaps there’s too much backstory to fit into the opening credit sequence. In 2012, on nearly identical equipment, they battled for “Best of The Rest” over and over again. Silly season saw each one looking for a chance to move to a factory bike, as each felt a satellite machine was incapable of winning a world title. One rider is courted by Ducati, then abandoned in favor of the other. This leaves one right where he started, but ironically, on a satellite Yamaha that will likely have better results than his rival, who has landed the factory ride both sought.

Dani Pedrosa has something of a reputation. Blisteringly fast when out on his own, but put him under pressure and he crumbles. Once passed, he is history, and he will trouble you no more.

There has never been that much truth to that accusation, and the MotoGP race at Brno should drive the final nail into its coffin, for what the diminutive Spaniard displayed on Sunday was the heart and courage of a lion. The race did not have much passing – just three passes for the lead in the entire race – but it was a genuine thriller nonetheless.

With the signing of Cal Crutchlow for another year with the Monster Yamaha Tech 3 squad, before the Czech GP even got started it was turning the page on another chapter of the MotoGP silly season. The racing too would prove to be pivotal to the Championship. A mix of good and bad weather during the week, Brno would prove to be a dry race, despite hosting a wet warm-up session.

With Dani Pedrosa on form all through Free Practice, the Spaniard’s off in qualifying took him off a step, as he had to ride his “B” bike, which suffered from more chatter. Despite Cal Crutchlow placing second on the grid for the race, the Brit noted what everyone already knew: Sunday’s race would be between Pedrosa and Lorenzo — and he was right.

The 2012 MotoGP Championship continues its trend of mixed weather, as riders had to contend with an evening rain that washed the Brno circuit. A decisive moment in the Championship points, the Czech GP already dashed the hopes of Casey Stoner, who after consulting with his Doctors back in Australia, was advised to sit out the Czech round and return back to Oz for surgery on the ankle he injured last weekend at Indianapolis. Also sitting out the weekend were Nicky Hayden and Hector Barbera, with the Spaniard being again replaced by Toni Elias.

It was not all doom and gloom on Saturday though, as Cal Crutchlow announced his new contract with Monster Yamaha Tech 3, ending the speculation as to where the likable Brit would land for the 2013 season. With Jorge Lorenzo only 18 points ahead of Dani Pedrosa, Brno is a critical round to nail down a solid lead in the Championship, though the Repsol Honda man has been gaining momentum the past few rounds.

Announcing ahead of Saturday’s qualifying session at Brno, Monster Yamaha Tech 3 has confirmed that it will retain Cal Crutchlow for the 2013 season, giving the French team an all-British rider line-up for next season, as Bradley Smith is set to move from Moto2 in the premier-class.

The re-signing of Crutchlow is an interesting move for the Brit, as he had been in the running for a factory seat within the Yamaha squad for most of the season, was also heavily linked to a ride in Ducati Corse for 2013, and there were even rumors of his return to World Superbike. With today’s news though, the speculation about Cal’s next season can be put to rest.

As we mentioned last week, Andrea Dovizioso agreed to take the factory Ducati seat vacated by Rossi’s departure for Yamaha. His signature, it appears, was subject to certain conditions, though. According to reports in the Italian media, Dovizioso demanded guarantees of support and development from Audi before putting pen to paper.

Italian TV station Mediaset is now reporting that Dovizioso has now received those guarantees, and has signed a two-year deal to ride for Ducati in 2013 and 2014. Ducati’s choosing Dovizioso over Cal Crutchlow – Dovizioso’s British partner at the Tech 3 squad had earlier been offered the ride at Ducati – is an indication of the the future direction of the Bologna factory.

The deal appears to signal that Ducati has accepted that they need to focus their development on building a bike to suit a traditional Grand Prix style, as displayed by the Italian. It is perhaps a signal to Ducati’s new owners Audi that they understand the magnitude of the problem, and that the loss of Valentino Rossi is being taken very seriously indeed.

Valentino Rossi’s imminent return to Yamaha – to be announced on Friday morning, Yamaha and Ducati having been forced to move the schedule forward once news of the switch leaked – will accelerate the final movements in MotoGP’s silly season, with the remaining open grid slots on prototype machines likely to be filled in very short order once the Rossi announcement has been made. Rossi’s return to Yamaha will be heralded much as his departure for fresher pastures at Ducati was, only this time the roles will be reversed.

First, Ducati will issue a release thanking Valentino Rossi for his time with the factory, and shortly after – minutes, rather than hours, – Yamaha will issue a press release welcoming Rossi back to the fold. The difference, perhaps, is that this time a love letter such as the one Rossi wrote to Yamaha after he left in the middle of 2010 is unlikely to be forthcoming.

With Rossi at Yamaha, that leaves five prototype seats still open: The factory Ducati left vacant by Rossi’s switch to Yamaha; the as-yet unfilled second Monster Tech 3 Yamaha seat (the first seat is for Bradley Smith, who will be moving up from Moto2 as provided for in the contract he signed with Herve Poncharal in the middle of last season); the San Carlo Gresini Honda bike currently being ridden by Alvaro Bautista; and the Ducati junior team seats, in a yet-to-be-decided structure with one or more yet-to-be-selected teams. So who will be filling those seats? And where does that leave the riders left standing once the music stops?
