When the first Xbox came out, they weren't able to utilize it either. But they worked throug the years and the graphics and gameplay got better and better. The same thing will happen with the 360, it took off where the Xbox left off, and progressivly, games will have better graphics and gameplay.

Kinda off topic, but Rockstar needs to work on the GTA graphics. The praphics are fine, but in San Andres, they meesed up horribly on the shadows to the point in where you couldn't play the game right cause you coudn't see the road or the player. The visuals for Vice City were pretty good, so far, thats the best one they released. Hopefully they will do better with GTA 4.
