In his tweets, Spencer also alluded to liking the concept of PC to Xbox One streaming. "I like the idea of Win10->Xbox One streaming but don't have a plan yet," he said. After all, it's becoming more and more popular with Steam-driven systems, so why shouldn't Microsoft snag some of that action on what is essentially a customized, downsized PC?I have fond memories from fifteen years ago, fragging fools on the Dreamcast version ofwith my trusty keyboard and mouse (plus I got to play!). Those poor controller-touting players just didn't stand a chance. So the remote possibility of playing this year's Call of Duty installment with a high-DPI mouse and keyboard on something comfortable like Corsair's upcoming "Lapdog? " That's pretty exciting.While this is obviously a move to bring Windows 10 PCs and the Xbox One closer together than even before, it's not just a move that benefits gamers. Microsoft could attract more PC-centric developers to their console platform, specifically those of the MMO variety. This could also open the door to more titles becoming cross-platform (simultaneous players on both Xbox One and PC) and even -- dare I say it -- an influx of MOBAs to the Xbox One?There's a downside to this as well: pushback from gamers who are plenty comfortable with their controller, thank you very much, and don't want WASD warriors having an unfair advantage in multiplayer battles. That's a fair complaint, and it should be interesting to see to what extent Microsoft implements this keyboard and mouse support. (Keyboard use is already possible in the Xbox One OS, but the addition of a mouse changes everything.)And we can't rule out the simplest outcome based on Spencer's tweet: That keyboard and mouse support maybe used for PC titles being streamed in to the Xbox One, and nothing more. That's a feature Microsoft hasn't announced yet, but it makes sense.My gut tells me we'll hear more about this at the annual Gamescom conference in Cologne, Germany next month.
