Eye tracking is a big game changer. I recall hearing John Carmack talking about it for future Oculus headsets. Only having to render small high res sections will save massively on GPU and battery costs. Standalone sets are just too underpowered atm, this would change that and let devs port bigger games over.
I love VR, but I hated the production behind setting it up/solving glitches, and being tethered to a cable. I played around with a wireless adapter for my rift, it was great. Having to take off the headset too often to fiddle with my keyboard was still a giant pain, especially as I wear glasses; smudge city.
Inside out tracking is probably miles better now, though the three sensors I have worked really well, especially for things like loading a bow behind your back. Having hand tracking glitches are as vomit inducing as dropped frames, at least severe immersion breaking.
Valve having their own OS for future games will also help streamline things.
I can't imagine anyone shitting on VR ever actually played it properly. I'll never forget my first go at an arcade with a vive. I felt like i was stepping into the Matrix, bought it right away.
