UFC 5 Realistic Ground and Pound Physics?

Will the Ground and Pound Physics in UFC 5 actually become realistic? This means every time I throw a jab, hook, or elbow on top of my opponent his head will actually snap or * in the direction of where the hit is taking place because from what I've seen and heard from sources they said that the ground and pound including the physics are the same exact thing as the one in UFC 4.
