Hmm.. all the store around here, didnt get SSX3 today for GC. But recieved their PS2 & XBox shipments of the game.
What the hell is EA doing??
Anyway the guy at EB let me change my pre-order and I got the PS2 version, though cause of a rather big mix-up that I wont go into here.. I can come back and exchange it for the GC version when it comes in. Of course if I want to do that...
But I want to be sure the GC has all the same features as the PS2, otherwise its not worth trading in.
My big things would be..
-Retains all the moves, but I dont know how they would do it without the 4 shoulder buttons.

-Dolby Pro Logic II & THX Certification
-16:9 / Anamorphic Widescreen Video Options
-Better Graphics / Better Framerate (not a huge thing on the list, but nice to have)
