Maybe the tackles will make "a little more sense". Sometimes in FIFA 11 i just felt that its not very convincing when a defender is pushing the striker over half of the playing field and then over the side line :D! From the first trailer the tackles look more realistic but a little exaggerated when people make a backflip after getting tackled. After all i think it can't add  much more to the gameplay since i believe in terms of physics FIFA 11 was near perfect. The features im more excited are the new Defender AI and if they finally manage to get a good network code. Also that strange shot that only has like 1 mph and causes every goal keeper to just jump over it should be fixed!!!

I'm excited to see how they change the physics of momentum and turning.  Its frustrating when players can just stop on a dime, turn 90, then cutback before your defender can stop.   
 
Hopefully they can ratchet up defense and goalie AI, but I think the attacking AI is pretty good for the computer teammates.   
 
It'll be hard to get too much better since it is already miles ahead of most sports games.  Lookin forward to '12

Maybe you could explain more about the engine ?
 
 
personally, i'd only get really interested if they borrow the destruction from Battlefield 3, you know, the same way BF3 borrowed the animation system from FIFA :P

What do you guys think?  Will it improve the gameplay?
