Windows on ARM only runs on lame processors like 8cx/SQ1/SQ2.

Apple Silicon may beat Intel/AMD and Apple Silicon is ARM, but that doesn't mean that ARM is beating Intel/AMD.

Yes. Microsoft is happy to oblige and Qualcomm seems to be ramping up their Snapdragon 8cx program, with it in a few recently released devices.

I hope bootcamp will be updated for the new macbooks eventually. I don't expect it to be out on day 1 but maybe a couple months after release?

Absolutely, better performance per watt means longer battery life. Windows already supports ARM. Microsoft doesn't really have a choice here but to improve support for ARM. Office on Mac seems like is going to be ready for Apple Silicon if that effort also helps Office on Windows ARM then they are half way there.
