Xbox’s latest video was ostensibly about a “strategic, multi-year partnership with AMD to co-engineer silicon” for the next generation of Xbox hardware–spanning consoles, handhelds, and more. But the end of the video is the most interesting part: This entire hook revolves around Windows.

Microsoft is confirming today that it’s working on a next-gen Xbox console in partnership with AMD. Xbox president Sarah Bond made the announcement in a minute-long video posted to YouTube, promising to deliver “an Xbox experience not locked to a single store or tied to one device.”

What is an Xbox? The answer to that has never been more confusing, but a new promo video from Microsoft teasing the future of its next-gen gaming hardware lineup gives an important clue: Windows. The company said it wants the OS to be the number one platform for gaming as it doubles down on a new multiplatform strategy that supports a variety of devices rather than being locked to a single console or storefront.
