A friend of my has the Oculus Rift 1 and 2. I've used 1 and it was pretty cool but the resolution was way too low and the comfort level was terrible. It made my eyes water and that just ended up with drops scattered on the screen. Didn't work well. Despite that it was still really cool even with the tech demos at the time. He says 2 is a lot better and I imagine VR is a huge improvement over that as well.
I've no idea what price point they're going for, but if they target ~$200 I think it'll do okay. Higher than that will be problematic unless critical/fan reception is amazing. Does anybody know at this point if the unit runs off PS4 or if it does its own thing somehow?
