Additionally, along with Zodd's post: Worldwide, all major PC headsets except the Pimax (because no one knows how to use it lol) were sold out from fall of last year through recently. It was physically impossible to find a single major PC headset anywhere except for, amusingly, Japan. Backorders for Valve Indexes and Vive Pros had waiting lists that were months long. I put my email in for a Valve Index back in November, and still have yet to hear back.
Every VR headset being produced is already claimed by someone who likely put their order in last October lol. And while COVID has had something to do with that since March, it does not account for the fact that it was also this way 5 months prior.
