Or more specifically Phil Spencer, the head of the Xbox division, discusses the Minecraft purchase. And what strikes me most about this short discussion is how committed Microsoft is to maintaining the Minecraft community across all platforms with Spencer even going as far to mention the PlayStation by name.
Because the thought running through most people's minds after the acquisition was that Microsoft might want to make the game exclusive to its own platforms. In practice, however, I think even Microsoft must be aware that there's massive amounts of money to be made by maintaining Minecraft's community wherever it can be found — including rival platforms. If people on the PlayStation or Android are paying Microsoft money for that product, that can only be a good thing.
On the whole Microsoft's attitude regarding Minecraft seems sensible. Very little has to change here. The Minecraft honey pot is there's to screw up, and in the beginning at least I think Microsoft understands that less is more. It'll be interesting to see how Microsoft evolves Minecraft in the coming years, but my guess is it'll try and stay as invisible as possible in fear of damaging the Minecraft brand. Time will tell.
