We don't link to screens offsite that much since we usually have most of them but Worthplaying has posted some screens from the upcoming Xbox360 version of Moto GP 2006, and damn do they look great. The shots look photorealistic, they really do. Now, you can say that a Motorcycle on a bare track would be easy to make look great, but there are shots with multiple bikes. Check this out.
and yes i know that there is no AA in effect in these shots.
