Just tested PES 2011 PS3 version from local gaming shop, now i really understand where the complain about PS3 version graphics comes.
One thing about PES 2012 demo i am still playing is the cpu ai, most all the time, i do not feel the cpu ai force them self to move forward if he does not seem to be able to dribble past me as in 1 vs 4 defender and when in their own box, they do not try to always clear the ball, they try to see the situation much more often. Pretty artificial intelligence ahead of 2011.
Player model collision detection, i believe everyone will agree on it becomes the best in PES series. Collision between both tesm mate or with cpu player model.
Tackling animation, i really like the way a player tackle by try to throw him self and make a side tackle if he is not that close to the dribble, it shows passion lol.

Regarding the animation, for almost similiar movement. IMO, PES 6 has better one. He rolls after landing. On another note of the goal itself, is pretty clear that the keeper does not expect the ball to be shot from that position, he is already move a bit forward. Sure, agree that it should be happen in very rare occassion.
