It looks like the Wii version this year wasn't a half-ass effort because EA actually included all the non-online stuff from the other consoles to the Wii version. Online has less stuff than the others but does get automatic roster updates.
at IGN having a "sizzle" video of all the new features and under new celebrations a high-five was shown as being a new TD taunt.
The game was rumored to have Tecmo Bowl like controls and gameplay but it looks like EA was lying because it doesn't unless its only in 5v5 mode or somehow they are considering the new power-ups as "Tecmo Bowl" style.
