A leaked trailer has been put up on YouTube; I don't know how long it'll be up since MS seem to be taking them all down but man this game looks nice. Not sure about the Kinect walk around the car stuff but I do like the idea that Kinect tracks your head so you can look into corners. The graphics and lighting are a step up too. Looks great.
Gah! That was insane! I think they may have stepped it up past GT5's level of lighting. Hopefully there is still options for controller usage rather than it being a completely kinect based game.
The only racing game i buy and play was RallySport Challenge for original Xbox. I wonder why the game not debuted in XB360.
