I read about this at IGN.com this morning, in fact. The developers annouced that there will be over 500 cars, so that much is fact. They demoed it at E3 and let IGN play with 20 of the cars on 3 tracks. This game sounds awesome. They also mentioned that the game will ship with a new steering wheel by logitech that actually turns around 2.5 times, like a real one, plus pedals and a shifter. They also talked about physics improvements and a more streamlined graphics engine so it will actually look better than GT3. I'm gonna get a ps2 just for this game. I liked the first one (played it w/friends all the time), but this sells me on ps2 for sure.
