New features for Minecraft for the Microsoft Hololens were announced. Cross gameplay with Surface and Hololens were featured. A fully 3-d Minecraft world was created via Hologram on a table. The world was shown to be manipulated via voice and hand controls, and the camera was manipulated via the same. The whole world of mine craft is at your fingertips, literally.
Personal anecdote: I never thought I would live to see tech like this showcased for the enjoyment of video games. Colour me impressed.
