Whenever i see manually animated characters they don't look authentic to me. The most realistic CG we've ever seen was in the Final Fantasy movie. Motion capture was used for all the body movements, except the faces.
Im pretty sure all the animation of the game (JK2) has already been done. From the videos we've seen the animation looks pretty sweet. So don't worry too much, i think its all coming along well.
No way, man. No way, man! Get yourself another patsy, man. No way am I wearing a freakin' wire!
