What you are seeing on the feed is not what John is seeing in the headset. The social screen is at 30fps, the headset is at 60-120fps. Also, the headset uses foveated rendering, John showed that off when he was looking at both sense controllers in the game, so at any point in time, if you are looking at anything on the social screen other than what John is looking at with his eyes, you will be seeing a blurrier image.
I think VR, like everything else, is not for everyone. I also believe that not all VR games need to or will be that physically exertive. Eg, my interest in VR has nothing to do with games where I have to be flaying my hands around to do everything. I want cockpit experiences, like GT7, an Acecombat game, and something like Wipeout in VR. And even when playing a VR FPS type game, I would prefer if the headset just replaces what I would have been doing with the right stick and the left stick just handles movement.
