The Oculus Rift is the real deal. They've done their research and figured out what needs to be done to make a good VR experience. 105 degree or higher field of view, low persistence, high frame rate, high enough resolution to get rid of the screen door effect, low input lag, etc. Without the headset meeting all of these criteria VR sucks. The reason it isn't out yet is because the technology isn't there yet, and they are working on getting it there.
Sony's VR solution doesn't even come close in any of the specs needed to be a good experience. It is just going to be another failed VR device like all the VR in the past. Same for many of the other "me too" VR devices coming out. People are going to get all hyped up about them, then reviews will come out and people will actually use them and realize how much they suck and the devices will bomb.
I hope that all these crappy devices coming out don't ruin it for Oculus.
