No. I'll admit I exaggerated by saying it'll only run MS Office but Windows on ARM is still very much limited. While it has made good strides in emulating the older 32 bit x86 ISA, x86-64, the standard for high performance apps for the past 15 years is still not supported and from what I understand performance even for 32 bit apps is nowhere near Rosetta 2 on MacOS. Even if we assume X86-64 support comes in 2021, the performance of virtualized Windows ARM emulating x86 is likely to be insufficient or at the very least unsatisfactory for many people used to virtualization on Intel Macs.
The point I wanted to make isn't that Windows will never, in any form, run on Apple Silicon Macs (It'll run in some form at some point.) It was that people need to get it into their heads that the era of virtualization & bootcamp as easy, low hassle, high performance solutions for non Mac apps is ending, and while I'm sure (hope) Apple Silicon will have its upsides, this isn't going to be one of them.
