I made this point in another comment thread, but I think MS would make a competitor to Unreal/Unity instead. Think of all the game engine talent they now have. The IW engine for CoD, Halo’s slipspace, WoW. They could readily assemble a team to build an engine on par with Unreal.

I could see it happen, but I feel a lot of these home grown engines are just too driven by tribal knowledge to be easily released to the public.

If it's any consolation, so too is Unreal, from my experience. A lot of the times the only documentation on a feature will be random Youtubers, and an official 3 hour stream from 4 years ago. Oh and the source code, of course.
