I'm sure Apple has prototypes like this internally. Apple clearly thinks AR is the way to go, and even tries to avoid calling Vision Pro VR. I think it's simply the tech isn't ready yet, and Apple isn't the type of company that develops in public. When we see what they have to offer, we'll be able to buy it within a matter of weeks or months.

Vision Pro could even be a red herring to get apps developed, so when their true mass market product launches it will already have thousands of native apps.
