Its coming to the Xbox360 in January and is supposed to on the lines of Forza 2 which means its a proper sim not the arcadey style of Grid which to be honest in the handling dept was rubbish,the game will feature all the tracks and cars from the BTCC with also GT's,Single Seaters,caterhams,and Mini Coopers appearing.
I think this will be or could be game to have in 2009 if the pc version is anything to go by:)
