It feels like Google wants there to be an answer to Apple Vision Pro, still isn't completely sold on the idea, but wants someone else to build it using Android. I'm not sure what other Android-using company would want to take that on, though. This feels a little risky even for Samsung; I'm curious what their "Project Moohan" device will look like... will it be crazy expensive and high-tech like AVP, or will it be something much more lightweight? The photos out there seem to suggest something lower-end than AVP, but it's hard to tell.
Meta uses Android for the Quest.
Will Meta adopt Android XR instead of maintaining their own Android fork? Possibly, possibly not. But they are definitely an Android-using company willing to take on the Apple Vision Pro seeing as they are already, you know, doing that.
I look forward to their definite announcement of Pixel Glasses in the coming months, as this certainly won't be something they completely forget about by next quarter
