Aye, it is more polished with respect to the feeling of the passing etc.
The cpu a.i. hasn't been improved much, played against Bayern at the top level difficulty and it still can't give you a decent match.
The cpu a.i. is still soooooooo kick and rush lol, really boring, which makes me think the be a legend mode will still be mediocre because of the a.i.
Really hard to gauge as we don't know what the % of final build it is and then it is remaining to see if the online lag issue has been resolved.
The demo is better than the last few versions, but still some of the problems from the previous versions hasn't been improved much by the look if it.
