You can't make something which does not exist better, now can you? You cannot add missing animations. I could care less about graphics (cause knowing that team, they will not fix disappearing crowds when forcing AA within drivers).
Much more needed information is on gameplay itself and seeing PS3 gameplay (IGN video was from PS3 not PS4 in case someone wondered why it looks much worse than all others vids from GC 2014).
That IGN video didn't look much more different to PES 2014. Even nightmares from GK howlers returned with it

Adam said we will get PC news this week though, so only can wait...
Och and Asim impressions from GC 2014 code are up:

Sadly, only apply to Xbox One/Playstation 4 versions of the game. :*
