Re: WWE '12
Well just look at UFC as a crappy example, but anyways. They moved it to an 18 month model, the only thing they've changed/added are submission and adding in feints and a few new animations.
Tbh 2012 looks miles better and different than 2011 thanks to the new engine, people cry on too much the games aren't that bad, yeah in some areas it's pathetic but still.
EDIT: Well either way they're not gonna do it, shed loads of people buy the game each year - even those who bitch. I'd rather they kept the yearly model, but if they changed to an 18 month model then so be it.
