Ok, I thought I'd be a nice guy and give up some more info on GT4.
IGN.com had a Q&A session with the maker of the game and he said they wanted to push the limits of the PS2.
Plus this would be the last game in the series to be played on the PS2 I guess they will keep making sequals if the game sells, but they will be on PS3
