Seems unlikely, only Meta and Apple have a comparable OS. Other manufacturers would have to either build their own thing or use Android XR.

Who are the "other manufacturers"?

I don't see many companies interested in this area. Sony has almost given up, Pico has had some major setbacks, and you know what happened to Apple's Vision Pro. There will continue to be investment, but likely by the same big players. There just isn't a lot of money out there, and not many companies can afford this.

Honestly, if Zuckerberg is no longer Meta's boss, they may have already shut down Quest entirely.

I was assuming that VR headsets or AR glasses would become mainstream at some point, like smartphones or tablets, with various Chinese manufacturers competing for the best price. But maybe you are right and that's too optimistic.

They've been around for awhile now and it's still not mainstream. What's holding people back now? Quest is pretty affordable. The quality is pretty good. You think a sleeker form factor will finally tip the scales?

Maybe not VR then. But perhaps AR glasses like Meta's Orion prototype. Though that seems somewhat doubtful as well.

Meta licenses their OS to other hardware players just like Google does. Apparently Microsoft, Asus and Lenovo are participating.

I believe Immersed is using Qualcomm Spaces for the Visor, but maybe that is lower level and Android XR builds on that as well?

Looks like it is close to this and Qualcomm has tools to simplify the migration to Android XR
