In an interview with The Verge, Xbox chief Phil Spencer revealed that such a feature was in the works, with the Xbox team currently looking to integrate mouse and keyboard support into the console:
We understand if you're going to go PC to Xbox, we need to get keyboard and mouse working completely so you could play those games. In terms of where we want to go with our platform, those are absolutely in scope of things that we want to do.
Given the diverse nature of PC hardware, Spencer mentioned that there are considerable hurdles to overcome before anything concrete is announced:
It's actually a little more challenging doing the encoding on the PC side to the Xbox, but challenge is good.
A timeline wasn't announced, but we'll let you know of any further developments as soon as we hear them. Would you guys be interested in streaming your PC titles on the Xbox One?
