At this point, it's easy to see Minecraft is (nearly) unstoppable, as the world-building giant continues to pull amazing numbers in sales, user registrations, and more, with the Pocket Edition of the game being the latest to pull in some impressive figures.Mojang developer Jans Bergensten posted via Twitter that Minecraft: Pocket Edition has sold over 21 million copies overall since its initial launch in August 2011, and its release for iOS in the following November.In addition to the impressive sales figures released from the Pocket Edition, Bergensten also announced that Mojang will be hosting an AMA-styled ("Ask Me Anything") Q&A session from fans with developers from the studio this coming Monday, April 14th, 2014 - the exact time of the stream is currently TBA.
