Today, during its BUILD Keynote, Microsoft introduced its Mixed Reality initiative, announcing two new headsets and a motion controller, but they didn't really show games.

At the end of the keynote, Technical Fellow Alex Kipman hinted to when we'll be able to hear more about actual games, and that's predictably E3.

Kipman promised that in Los Angeles we'll hear about the "windows mixed reality content story," and it'll be certainly interesting to see what games it will include and if it'll expand to consoles.

Speaking of consoles, during the presentation we got a quick look at what appears the application of mixed reality to Xbox Live, and you can see it below.

While it wasn't mentioned by name and no further details were provided, it could be a prototype or a concept visualization of the "Metaverse" mentioned yesterday by Xbox Division Head Phil Spencer, allowing gamers to actually interact with their friends' avatars in a mixed reality space over Xbox Live.

We don't know much about it yet, but it'll be interesting to see how and if we'll hear about it at E3.
