Graphics for a start, obviously, also, in create a superstar mode, you'll have 5 extra layers to use in the PS3 version.
But the huge major difference is Highlight Reel mode, which is not in the PS2 version. This allows you to create videos using match footage. Its a pretty good tool i've heard.
Also, the PS3 version has online capabilities, unlike the PS2 version.
Thats it.
