Future Skully AR-1 owners will have to continue waiting for their helmets, as Skully has once again pushed back the delivery date of its heads-up display powered helmet.

The announcement is another blow for the San Francisco based startup, as Skully has gone from the media darling to full-blown vaporware-pusher over the past two years.

We say this because Skully first launched in 2013, with promises of helmets in the hands of consumers by the end of 2014. That date was then pushed back to May 2015, in conjunction with Skully’s Kickstarter campaign launch. That date would be revised again, this time to the end of the year 2015.

Now well into the fourth month of 2016, Skully is pushing back its delivery date again, though it isn’t giving a firm timeline when the production units will finally reach purchasers. It should be noted that as of this date, only a handful of pre-production units have made it the hands of specially chosen evangelists buyers.
