My thought was that the cameras won't be able to rotate a center
point like our head is able to. Tying the camera rotation to the head
movement instead of eye movement (which is what the cameras will
actually be able to do in that scenario) might feel unnatural. Of
course, tracking eye movement instead of head movement is a much harder
thing to do, particular when your eyes will be covered with LCDs or
something along those lines.

cause vertigo or something similar, due to the camera rotation not
matching what your head motion is doing.... what would be better is some
way to track your eye movement and position the cameras that way. That
way the camera motion would resemble what your eyes are trying to do.
