I run a Mojave VM on my Windows 10700 System. It runs well though expect video artifacts. There is a way to integrate the video for much better video performance - it involves running QEMU-KVM and I'm not really sure how to go about doing that. It can be done on WSL 2 as well and I'd love to get that working but I looked at the directions and didn't bother trying.

Then again, the simplicity and performance of an M1 Mac is enticing. But like you said, there are a lot of interesting rumors right now. Especially around a smaller Mac Pro.
