A bit of info tucked away in the Xbox Game Pass for PC announcement that I thought was thread-worthy on its own.
Between this and Halo: The Master Chief Collection, I think it's safe to assume that major PC releases from Microsoft will be launched on both the Windows Store and Steam going forward. Hopefully Halo Infinite also comes to Steam, and maybe some of their back catalogue as well.
In March, we announced that Halo: The Master Chief Collection will come to PC later this year, launching on Steam in addition to the Microsoft Store on Windows. We will continue to add to the more than 20 Xbox Game Studios titles on Steam, starting with Gears 5 and all Age of Empires I, II & III: Definitive Editions. We know millions of PC gamers trust Steam as a great source to buy PC games and we've heard the feedback that PC gamers would like choice. We also know that there are other stores on PC, and we are working to enable more choice in which store you can find our Xbox Game Studios titles in the future.
