I think discreet 1080p screens is still pretty low for VR. Considering you blow it up to 90 degrees horizontally (which is only half of what you're aware of and can reach by turning your eyes only) it would be like sitting half a screen width from your tv, or 1.5ft from a 42" screen.
Plus the more you blow up the size the more frame rate begins to matter. Current consoles can't handle 2x1080p at 60fps.
I really want to try it, but the numbers all point against it becoming a big success. Either it's very expensive with still lacking dual 1080p screens and struggling games, or more affordable with dual 720p which will only work well with simpler stylized games.
I would still buy a $300 dual 720p version to experience 6 degrees of freedom for looking around. I won't get my hopes up that it will become my primary way of playing games.
