so it's PS4 + box + headgear. No indication of what the extra box does yet but it's quite likely taking some of the processing burden.

Edit: Been reading about, I think it performs reprojection, that bumps the fps up to 120, it works by averaging 2 frames and creating a new one in the middle. But yeah you're right, that seems to be because the PS4 can't push 120fps at 1080p natively, it can just manage 60fps.
