Actually, you're both wrong.
Shaba Games: 360 and PS3
Treyarch: Wii
Amaze Entertainment: PS2, PSP, DS
Aspyr: PC (confirmed to be a 360/PS3 port)
360, PS3, and PC are all rated T for Teen, which is the official rating of the game. The screenshots, trailers, and all of the previews up to this point are all from this version.
Wii is rated RP for Rating Pending, it's possible it could be T or E since Treyarch is developing the game.
PS2, PSP, and DS are all rated E10 for ages 10 and up. The PS2 and PSP version is subtitled "Amazing Allies Edition" which can only mean that extra content has been added to make up for some type of change in the storyline (graphics will be an obvious change).
