I don't see VR getting to the point of being a mainstream product for gamers as it doesn't add a significant novelty that can be enjoyed easily. Like early radio was a hobby interest but once vacuum tube technology made audio amplification a reality more people (even those who weren't technically inclined) were able to enjoy radio programming and thus the audience exploded. VR needs to be as easy as closing your eyes and going to sleep to enjoy properly in my opinion. And that sort of interface is probably a century away at best.
