Xbox boss Phil Spencer has via Twitter announced that he will visit a Windows 10 event next month to talk more about Microsoft's plans for gaming on the PC platform:
"I'll be focusing more on what we are doing on Win10 in January, it's time for us to talk about gaming on Windows."
There has recently been rumours about Halo games heading to PC, and the company has also sought out opinions regarding a port of Killer Instinct to PC. It is believed that Microsoft wants PC and Xbox One to share a common ecosystem and therefore get the maximum amount of games and services on both.
They might also try and launch a new gaming service on PC to compete with others like Origin and Steam, though after Games for Windows Live we won't be pinning too much hope on this.
