Yamauchi was also asked about Gran Turismo 5 feature list, which GTPlanet managed to grab before it was quickly pulled from Polyphony Digital’s website. Although he comes short of explaining why it was posted, he confirms the information is true.  Yamauchi goes on to discuss how the new damage feature will affect a car’s handling characteristics, and goes on to say there will be “real NASCAR races.”  Finally, Yamauchi retierates that the game will run at in full 1080p resolution at 60 frames-per-second.

Well well well....60 fps @ full 1080P confirmed and the car damage will have affect in the car's handling.....Awsome.

Yeah that would be fair.

It better come before Christmas :-/

About the last bit. That's what I don't understand about the internet you have people claim the Naughty Dog are gods and the best dev in terms of technical terms when there game is only 720p 30FPS while developers like Polyphony Digital and Santa Monica doing 1080p 60FPS games (55% more the resolution and double the frame rate).

Polyphony are GODS

Woot Woot!!!!!!!!!
