The fact that industry and special use cases like NASA are using it means that some consumer version will probably always exist, and if industry is finding uses for it, consumers might also find uses for it. VR could also fail catastrophically as a consumer product and just be something that's exclusively used by industry, but I don't see VR going away for good. I think it's carved out a healthy enough niche for itself at this point that some version of a VR/HMD industry is going to exist for a while.
