Any particular insight why 2022?

Hololens 2 has shown that it isn't so easy to advance the field.

I don't think an Apple device is forthcoming or likely to leapfrog.

Facebook, Apple and others are releasing their first AR glasses then.

And there will be approximately zero non-gimmick software for them until at least 2032, if it ever materializes at all.

AR "FaceTime" (beaming in an avatar of another person to spend time with) will be a killer app.

But you aren't "spending time" with that person. You're spending time with that person's poorly rendered avatar. You can't even hear them properly. You can't see them at all. You can't touch them or read a lot of the nonverbal cues. And for the privilege of not being in their presence, you also need to pay several hundred (if not thousands, this being Apple) dollars, and both sides need to use Apple products. I very strongly suspect that all but the most ardent Apple fans will pass on this generous offer.

Passthrough AR isn't glasses AR, and is much more likely to be rapidly made capable. Lynx-R launches in Q1, and Meta's and Apple's headsets will likely use passthrough AR next year.

I definitely hope for something novel with video see-through HMDs as they used to call them in 2002 [1] when I last worked on them. Latency wasn't solved last I checked and viewpoint offset is still an issue that throws users off.

Latency is pretty good on Quest 1 - I haven't tried Quest 2. Looking forward to getting a Lynx to gauge how close we are to something good.
