Our eagle-eyed internet informants have spotted Trackmania 2 footage - actual game-being-played-by-a-dude footage! - and I've posted it below. Might be one of those Soon To Be Zapped typed situations, as we don't seem to have got this from Mr Ubisoft directly. It looks suitably slick, and just about mad enough to be Trackmania.
And yes, I used the same screenshot again, wanna fight about it?
