This seems unlikely. I could see this make a bit more sense if Microsoft wouldn't have screwed up their mobile platform so badly, but if you just serve desktop/laptop, a switch to arm doesn't make sense. I expect x86 to catch up enough to not justify the performance impact of even really good emulation on arm. Usually if you go Windows it's because of its huge software library and backwards compat, so I wouldn't bank on having all the important apps be native arm after a year or two. Everyone else is already on a different platform.
