Well it's something they want to implement this year since people beat them over the head with it especially when the 360 game did not have it. Madden and NCAA will most likely have it this year. Arena football is the Madden engine with 600 animations tailored for Arena style play
Unless I misinterpreted this. Look at the language. There are thousands in the game with 600 NEW and UNIQUE Arena Football style animations. So speed up Madden, add 600 new animations that fit Arena Style. Shorten the field length and depth, ect and you have Arena. I'm not saying it won't be a good game, but what I am saying is since the pile on tackles have been added to the ENGINE then expect to see them in Madden and NCAA, games that share the same engine.
