The problem that VR had was the cryptocurrency craze happened at the same time which shot up GPU prices. Add to the fact that ram prices also went through the roof and the cost of the headsets. But now, GPU prices are finally returning back down to how they were. And RAM prices are forecast to drop. Not to mention headset prices are also going down. Add in new advances such as going wireless via wigig and 4k per eye, and there is still plenty of room. Back in early 2000s, people thought smartphones have no future too. I'll tell you this, if they create a pokemon game for VR, you'd have millions of VR systems sold out in less than a month.
