A month before the Xbox One even launched in 2013, Microsoft was talking about bringing keyboard and mouse support to Xbox One. Then back in January of this year, Spencer said PC-to-Xbox One streaming is something that Microsoft was "really looking at." He explained at the time that this feature is part of Microsoft's grand "vision" for Xbox games overall, following the news that Xbox One-to-PC streaming was in the works.
Also on Twitter today, Spencer confirmed that Microsoft remains "on track" to deliver a new update for Xbox One that brings Windows 10 integration to the console. "You'll hear more about the dates soon," he teased.
Microsoft said previously that Windows 10 integration for Xbox One would be coming sometime "post-summer," with Xbox One Preview members getting to try it first.
