Can't remember the site I read it on last night but I'll try and find it.
Pretty much:
New physics system
you dont just hit the players, you can miss and just catch a bit of their leg so its not just straight hits.
sticks aren't always on the ice
broken sticks
new faceoff mechanics
you can jump over players
shoot the puck while you're down on the ice
