They're far too hulked up for my tastes, and the way they move weirds me out. It's like they're stiff and not capable of fluid locomotion from head to toe--the legs and arms might be moving fast but nothing else looks like it fits with what's going on there.
I will say, though, that the graphics look beautiful in still shots. I think the team will handle this in time. Maybe not a total overhaul in year one, but at some point.
If they get the basic gameplay stuff right I wouldn't let models hold me back from playing the game.
