While WWDC will be the two-year mark from their "we're transitioning in two years" statement at WWDC 2020, I'm inclined to give them until November 2022 since that's the two-year mark from that first batch of M1 products they released. They'll probably use that as their backup/caveat..."we said 'two years'...we never said when that clock started. In our mind, it started in November 2020."
So if things don't pan out as hoped/expected at WWDC, keep the above in mind. But it would be nice to see more AS Macs unveiled/released, sure enough. Last week was kinda out of nowhere, that whole Studio thing...
