It's official: Minecraft is getting a Pocket Edition and here's some video to prove it! The port will first arrive on the Sony Ericsson Xperia Play before is comes out for other Android and iOS devices.
Mojang Studios probably chose the Xperia play because of its dedicated gaming button feature. The price of the game isn't known yet and there has not been either a release date or exclusivity period mentioned yet, but this has all been confirmed by the makers of Minecraft themselves.
Minecraft will finally leave beta status on November 11, 2011. When it finally ships, it will be available for €20.00 ($28.87); right now it's still in beta and goes for €14.95 ($21.58).
