To be fair I was expecting to see smoother transitional animations and more refinement in general.
I watched the video a few times now, looking at the gameplay in the background, in fact my negative point is that it does look a bit fast doesn't it..
What i can see from the video and from the feedback is that this game looks to have that responsiveness it lacked in PES 2011. There wasn't any example i saw of a player looking unresponsive.
That was the big issue with why PES 2011 looked so jerky, the stumbling, collisions where players would be locked in animations (you see this with keepers and shooting etc.. Also things like you could have 2-3 players standing next to each over as if like statues. I didn't see any of that in the video.
So as it stands for me the animations are just about good enough without again being spectacular!
