Money quote:
"We're also pleased to report that – unlike the PC, PS3 and Xbox 360 game – you'll be able to play through the entire campaign mode in splitscreen co-op with up to four players!"
Other versions do get a deeper single-player campaign, but I have big hopes for the multiplayer Wii version, with several multiplayer modes that sound like a blast.
