Apparently my research was less complete than I thought.
Anyway, it was always going to be easier for Microsoft to make an XBox emulator, regardless of the platform: they know how it works better than anyone else. I wouldn't be too surprised if they had a working emulator to run XBox games on windows, be it by compiling the source code for pc, or jit or an interpreter. I could see it making it simpler to write the games. Of course if they did have one it wouldn't mean it would ever be released.
