content: Well since Mojang - team behind Minecraft - got acquired by Microsoft, it's not ludicrous to expect Microsoft to show off Minecraft together with their AR concept. But generally, I suppose it's a great advantage to create/manipulate models that no longer take up physical space, and can be easily portable. And that's not just limited to games. Pretty much any business can make use of holographic models to realise a vision or concept more easily, and get people on common ground of said concept. Oh yeah, I also get annoyed whenever people lump AR into VR. VR completely throws you into a new reality, while AR melds it with the real world. Different things!
