i think VR will be a reasonably successful fad, much like kinect. it will sell a few tens of millions of devices. most games will be developed for not VR but many will be "better with VR". only a handful of games will be "VR exclusive". for those that enjoy the technology it will be a very deep, engaging experience but the mass market will not fully embrace it because it is too dorky. eventually people will lose interest and the technology will fall out of use when the next amazing whatever comes along.
in the short term AR isn't ready, it will be glitchy and unreliable. in the long term AR will be terrible for the deep kind of gaming people on this forum enjoy, we want to be put into an engrossing world not play in our own boring worlds. however, AR will be fantastic in revolutionizing the "smartphone" and drastically change the way people interact with their information: phone calls, texts, navigation. there will be a bunch of shitty "AR mobile" games on these devices of course but people on this site will never respect them. it will make much more money though from an investment perspective.
