The YouTube blunder has prompted an official announcement, although there's not as much in it as usual:
The Ultimate Collector Series R2-D2 – the best-loved droid in the Star Wars galaxy!
10225 R2-D2™ Ages 16+. 2,127 pieces , US $179.99, CA $229.99, UK£ 149.99, DE€ 179.99, DK 1499 DKK
Presenting the iconic R2-D2 as you’ve never seen him before. Everyone’s favourite droid from the Star Wars galaxy is now part of the Ultimate Collector Series. The model features fantastic detailing, such as retractable leg, front panels that open to reveal a universal computer interface arm, a circular saw, rotating head and two fold-out front spacecraft linkage control arms. With the included fact plaque and R2-D2 minifigure, this diminutive model is the perfect addition to your LEGO® Star Wars™ collection.
Update: I've been sent alternative images of the set which you can now see on the set details page.
At least we know the prices now, and I'm told it's scheduled for a ’beginning of May release’: May the fourth, probably!
The video is now on a different platform rather than YouTube; I'm guessing we might have seen the last of LEGO's use of that for product release videos :-)
