Yes there was a Big Spike in VR interest around Oculus, and most of the people who bought one have it sitting in a corner collecting dust...
But a significant subset of people continued to use it, and their usage is steadily growing. There are huge numbers of people willing to pay $500 -$2k, on each new device that comes out, just to "see if its ready".
There are tons of people who work from home on a couple monitors, who WANT to have a VR work setup that gives them screens the size of walls. Obviously the comfort, battery, and visual performance is not there yet, but most people have a feeling that would could just be a generation or two away from it.
I would guess that more than 50% of hacker news readers over 40 years old had an MP3 player BEFORE the iPod. They were all garbage and completely replaced when the iPod came out, but for the 2-3 years before the iPod, all the early adopters new something like that was coming and they were hungry for it.
I feel that's exactly where VR is.
