So far, we haven't seen anything of the game, but I believe it's due to the damage model Polyphony Digital wants to implement into the game, I think they are still working on that very hard, and they have had problems with Ferrari not alowing their cars to have damage in GT5.
Knowing Kazunori Yamauchi and how he is a perfectionist, we can expect a game as massive as Gran Turismo 3, hopefully.
