They can't do anything about that. If that's your issue with VR, you're out of luck. It's not for you.
They've been working on the head tracking and latency to solve the problem for people who are sensitive to delay or errors in head tracking. Fortunately I'm not sensitive to either issue, and could enjoy head-tracking VR much more primitive than the upcoming devices. Playing F.E.A.R. on an emagin z800 years ago was an excellent experience that actually induced fear while playing.
