The main changes to Wolf are his down attacks. When the opponent is face-up, with head closest to Jacky, he can grab the opponent by the shoulders and flip them over him. YOu can see this in the promo vid. When the opponent is face up with legs closer to Wolf, he grabs both heels, and does a nice testicle-stomp. Not sure if you can escape these or not. He does have some other small changes here and there. No amazingly different combos revealed yet.
