I think this is incorrect. Specifically the Windows ARM support. Official hardware support page indicates that the Windows version requires x64. I unfortunately don’t have the hardware to confirm for myself. But Blizzard is the kind of company that would have made a blog post about that.

This is neat, and exciting that Windows emulation tooling is progressing! It seems like there’s a lot of work hardware vendors would need to do in order to make Win/Arm viable for game devs. I really wonder if that’s ever going to happen.
