Microsoft Xbox chief Phil Spencer said Thursday that Microsoft is working to make Windows 10 "the best operating system for gamers, traversing the PC, phone, and console," and announced the return of the Xbox One holiday pricing of $349 for the foreseeable future. In a video Spencer talked about what's new for the Xbox One console in 2015. Earlier this week, Larry Nelson, Microsoft's chief point person in the Xbox One community, revealed the Xbox One updates for February.

Microsoft announced the price re-drop along with the fact that the Xbox One was the best selling console in the US for December.

So as we did during the holiday season, we have two almost similar consoles (Xbox One and PS4) with similar game libraries, one of them for $349 and the other for $399.

Spencer also mentioned Microsoft's Windows 10 event coming next week.

"I'm excited to be talking on Jan. 21," Spencer says in the video. "We have speakers coming up, talking about Windows 10, and the great work that we're doing there.

"For the Xbox team, this is the beginning of the discussion with fans about the work we're doing to bring gaming to the Windows 10 operating system," Spencer said. "It's really nice to be able to finally begin to talk about this; we'll continue the conversation throughout the year. We remain committed to gaming on console, but we know that we have fans and gamers that also play on PC, and on phone, and it's important that we build out the features that we have, learning what we've done on console, and working to make Windows 10 the best operating system we've ever created for gamers on PCs. "

Microsoft has tried to build out unified apps for Windows Phone and Windows, providing a similar experience for those who own both platforms. Spencer's world allow us to speculate that Microsoft's next step is to allow streaming of Xbox One games hosted on the console across a network to PCs.

We'll find out next week.
