More information is promised for the upcoming MineCon, but what we saw was a real working demo with real working code. And honestly, it looked out of this world.
Ever wanted to just play Minecraft looking at your wall? Better yet, how about seeing your creation rise up out of your coffee table?

You can also use the Xbox One controller to play in a more conventional fashion, but you'll probably not want to. There's still much to learn about the future of HoloLens, but this early look at Minecraft has us thirsty for more.
