Personally, I'd wouldn't count out electronic varifocal coming in Quest 3 (2022?) as it looks like the Half Dome 3 prototype was already TRL6 w/ the electronic varifocal, and Facebook has been making additional moves like acquiring Lemnis earlier this year, which already has a similar-approach full-stack commercial varifocal system. Varifocal would be a huge win for comfort/long-term usage (eg, if FB continues to push on the remote work/productivity/collaboration use cases). While I'm less sure on foveated rendering (although I'm really impressed by DeepFovea https://research.fb.com/publications/deepfovea-neural-reconstruction-for-foveated-rendering-and-video-compression-using-learned-statistics-of-natural-videos/ https://research.fb.com/publications/deepfovea-neural-recons... I wonder what kind of rendering pipeline will be required), I think basic eye tracking will be coming w/ Quest 3 as well - it's not only needed for DeepFocus, but also their Codec Avatars. The stuff that FB has been showing off the past few years is insanely impressive - I think their mixed reality approach beats the pants out of what MS has been doing. I'm really curious to see what Apple has been whittling away at in secret - I'm doubtful if it can compete, but who knows? Google seems a bit out to lunch on all this.
