I think it would be amazing for dayz to support the oculus rift, the omni virtuix (a virtual reality treadmill coming out that is affordable, and weapon tracking of some sort (razer hydra, or similar 6 dof gun controller), This would make everything simulate real life. You would aim and shoot gun just like in real life. Run and jump. It would make for a very immersive game. Not to mention additional press for being one of the first true virtual reality supported games.
