One thing I rarely see mentioned or discussed is the "longevity" of VR interest amongst users. As a (former? I'm not sure yet) VR enthusiast and adopter on the high end of things I noticed that the novelty wore off really quickly, after ~1 year of owning my Index my usage went from somewhat regularly to barely anymore and for most titles with VR support I prefer playing them the regular way and the VR-first titles can't get me to set it up, or were "onetime" experiences (like HL Alyx, which is one of maybe ~3 VR games that really felt enriched and improved by the VR experience, in hindsight).
From friends and colleagues of mine I hear similar things, VR headsets collecting dust already.
