Hard to tell from the distance, but it looks cleaner. Not immediately noticable compared to current gen but it looks like all the edges have been cleaned up.
I wasn't expecting a graphical revolution, but was expecting much more from them in the player movement, foot plant and momentum aspects. Based on these videos I am going to switch my pre-order over to AC4 and wait a bit after release to see how the game plays out because right now it looks too much like current gen. Definately not a day one buy for me anymore and has me rethinking Madden as well if FIFA was the peg that EA was hanging their next gen hat on at launch.
