Haven't you learned by now that GT5 trailer videos are edited?
So what's to stop them from doing so to the screen shots hmm? I realise GT5:P is a couple of years old now, but i wasn't impressed at all with the graphics, especially with the lack of Anti-Aliasing, so i can't see the graphics changing too much up to the release. Oh wait, there working on dynamic weather and time cycles...OH! And damage too, but only for certain cars! How cool. Oh, and rollover too! Wow, so i guess in the huge ammount of time it will take them to finally release the bloody thing, they might be able to fiddle with the graphics after all! AWESOME!
