Long story short...
*Xbox 360 and PlayStation 3 versions to feature 66 playable people. Obviously the leak didn't reveal everybody...
*Create-A-Belt is OUT. This is apparently due to it being a rarely used feature in the game.
*Create-A-Tron is a distinct possibility for future editions of the game.
*Tribute To The Troops arena is 100% confirmed IN.
*No trophies for PS3 players.
*PS3 is graphically inferior to X360 at this point.
