All the Willow Springs footage looks really good, considering how old the PS3 actually is it sure didn't look it on the replays! I don't know the real track at all but it's nice to see something that isn't smooth and flat, like going off track you really see how uneven the dirt / sand and how it falls away when the track's a little banked / cambered.
Silverstone looks good too but kind of has a look of "existing tracks" about it, I don't mean that in a bad way just that it has that sort of familiar look with the buildings and grass and such though it's probably because it's not as wildly different as Willow Springs is scenery wise. Good to see a little more of the smoke effects too, that definitely seems to have improved quite a bit and should make those Drift Trial photo shoots look even more awesome.
I do like what we're seeing of the new UI too, like the tire indicators going yellow is much nicer than the pink stuff we have right now.
