VR has the same issue, in my mind, as motion controls: even at it's absolute finest, it's *contextually* excellent. It's got a specific subset of games in which it provides worthwhile improvements to the experience. It has a broader range than motion control interfaces. But still, same kind of problem.
Lastly, VR has a lot of barriers to entry. It's expensive, it causes motion sickness to random individuals with completely random games, it's highly isolationist and cuts you off from your surroundings which makes it inconvenient. It's just not practical for mass market appeal, not at the moment. And I certainly don't see it replacing traditional gaming wholesale or even the majority of it. Far too many genres where it's not worth it.
I do think it can succeed as a part of the market. But I don't think it is the revolution where it is the only future.
