I have to say, I'm definitely warming to the demo (Xbox 360). All good PES games take some time to transition, and the good games tend to grow on you, adding that longevity.
As far as the core gameplay and animations go, I'm really quite liking it. Shooting feels quite great, passing is obviously an improvement over the generic system a few years back although it still is a little sloppy and inconsistent I think at times, slide tackling is good. Overall, it's quite good so far I reckon.
My main gripe is still of course the jumping and loading mid-game which occurs quite a bit. Also the cringeworthy goalkeeping, and sometimes dribbling magicians it seems of the opposition are beyond frustrating mind, especially the goalkeeping which has plagued the series for years now. I've noticed as well player cursor changing out of the blue. On the last game, the problem was that when you clicked to switch, it would sometimes switch to the wrong player - but now it seems that when you're controlling a player, sometimes the cursor will simply switch anyway of its own accord. I was controlling Assou-Ekotto earlier, and went to lunge in with a slide tackle, only for the cursor to have been switched without my control meaning I slid with Gallas instead (who was 15 yards away from the action marking someone), meaning I wiped out the opposition's striker from behind, receveiving a straight red card. As I say, it's happened a few times since, especially with the odd slide tackle, so it really could do with being addressed as I can see it being another problem.
