Those pictures are CG NOT actual in game pics. cobragt, I wish those were in game shots but hell no I mean look at the detail on that! compare the rims of that GT40 with the rims of the cars we see in the replays. PS2 simply can't push that amount of detail. (maybe she can... with 20 frames per second) it's common sense. please don't push this thing any further maybe I shouldn't even wrote this post but I think that you, as other people are waiting to see a miracle! you'll have a big disappointment when you actually play the game and see that in fact the PS2 is being pushed to the limits but it's not showing what you expected.
IMO GT4 is going to be so good it's not even funny but graphics like that???? naaa. wait for PS3...
Note: I do not wish to offend anybody, this is just my point of view
