I don't doubt the initial interest, but the long term success is questionable.
In theory, eventually. But for now it requires an expensive helmet and will for a whiles, and that will in turn affect whether people are really interested or not, and that will in turn determine whether future investment is worth it or not.
eg. 3DTV. It was a novelty. It needed active glasses, or fancy displays. It could have become cheaper and better, but consumer lost interest so TV companies didn't bother investing so much. So no 240 Hz active active glasses, or 8k autostereoscopic displays.
Or Kinect. Amazing tech, massive appeal. Short lived, people gave up wanting to play wiggle games on the whole, devs stopped supporting it, and instead of the market becoming saturated with computer vision interfaces and gaming and wild R&D pushing the tech (and there were plenty of startups) it's all gone quiet.
VR is going to have a significant early impact, I'm sure, but I think its long term future is as unpredictable as every other new tech.
