What does this tweet mean? Well we could be seeing some new things on Windows 10 that have to do with the Xbox One.
I think that they are doing something with the universal apps and maybe just maybe letting you play your Xbox One games on your PC which would be awesome, but we can just speculate for now.
@RpLayy 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.
