Don't hold your breath. With Microsoft recently adding to their long list of pathetic and childish Anti-Mac ads in favor of the Surface it's highly doubtful they will allow Windows to run on the M1 through VM or any other way for that matter. They don't want to lose sales of their own PC to M1 Macs. They know they will if they allow Windows Arm on M1 Macs.I'm curious if Parallels could somehow negotiate with Microsoft themselves to be an OEM, and sell Windows ARM themselves and install automatically thru the interface, without having to get it externally.
Otherwise I think if that doesn't happen (or MS doesnt allow purchase of ARM separately), Parallels as a company is probably dead in a few years, once the old Intel Macs begin to be outdated.
