I'm pretty excited to see it in action in just a normal game play sense and not a video just showing crazy animations. I have a feeling that it will also now have a huge impact on fouls and injuries. In terms of fouls, more called and properly called. Injuries, injured areas are those that were contacted.
Time shall tell, but just the fact they they had an outside team working on it for two years excites me. They took their time and allowed it to be done correctly instead of just trying to jam some type of it into FIFA 11.
