Pretty sure Havok engine is used for physics, but not artificial intelligence. I do agree that Yukes or Visual Concepts needs to completely re-write the A.I. and make it entirely customizable. That way people can go in and make high-flyers (RVD, Sin Cara and Rey), power (Ryback & Henry), brawlers (Cena & 'Taker), submission (Bryan and Del Rio) wrestlers and everyone else more unique. The shoddy A.I. has held this series back almost more than anything else, IMO.
