A teaser of the next game from Blackrock Studio (Pure) has found it's way onto Youtube. It's short, predictably blurred, but shows of a game featuring street racing a far cry from the dirt tracks and ATV's of Pure and more akin to the likes of Burnout. The teaser ends with a message that there is more to come on March 11 - the date of the official announcement perhaps...
It looks fairly official for a "leaked" video, but there is always the risk of it being "bullcrap". I'm betting it is legit, though.
