Re: A fad?
The sort of gaming that you're talking about is itself a niche market. Even if 100% of such gmaers adopted VR, that still wouldn't count as being "mainstream".
VR has a few obvious areas where I expect it to be rather popular. Games is one of them. Various industrial applications are another. It's hard to see how the gear would achieve wide adoption outside of those areas, though.
