actually in terms of benchmarks, the graphics are going to be almost identical, seeing as how Gt3 pushed PS2 to it's graphical extreme. I'm sure it'll be slightly better and all, but graphic wise is going to be almost the same, the only difference is going to be how much time they put into those graphics i.e. Landscaping will contrain more parts as apposed to repeating 2-3 diff images for dirt, they may have 5-6 which is a huge difference to the naked eye. In terms of the "grand Canyon" I don't see what's so amazing about that. The background is practically a still picture, the playing feild is rivaled by alot of other rally games. But, we shall see when it comes out.
