I'm skeptical with PlayStation's VR. In order to avoid motion sickness it has to be over 60 FPS. Normally I'd say that's not a problem, the PS4 is totally capable of achieving that at 1080p. BUT... since this is VR, and VR is 3D... there are two screens. So that load is doubled. Which leads me to assume that VR games on the PS4 will be pretty limited graphically to compensate.
Totally happy to be proven wrong, but as it currently stands... Oculus or bust.
