Well overall it's much better than pes 10.
The movement and the weight of the players is really felt and overall the animations are much better and less robotic. Still not as good as Fifa's, but from a distance, the animations looks really good. In close up, they're at times similar to pes 10, but with weight added.
So overall the animations are much improved.
The trick system CAN BE GREAT IF ONLY THE DEFENDING WILL BE IMPROVED.
From the first game, I saw some nice defensive challenges, but when messi had the ball, I started to worry, because he seemed untouchable.
So if the defending and goalkeeping are improved, then this will be awesome.

BTW the passes are looking much better than before FINALLY.
Here's hoping. I also want the game to be difficult. But I cannot comment on this just yet.
So the only downsides I saw from the trailer were the defending and goalkeeping. I hope they'll improve.
