They’re shipping pancake lenses, color pass through, and depth sensors on the Quest Pro and Quest 3. Those were features on the last batch of prototypes a few years ago. Some features from prototypes haven’t shipped yet like their ultra high brightness display or varifocal lenses but I doubt they’ve canned them. I’m glad they’re being so open about this research, along with the release cadence they’re building up for new headsets it inspires a lot of confidence.
