I can only assume that MS are going to insist on a sequel with all of the 'NextGen' trappings we've come to expect from them. Minecraft2: MasterChief Edition. With Kinect! And day1 DLC! And product placement... (Use the new MTN DEW powerup to double your building speed! Feed your animals DORITOS to improve their stats!)
Good for Markus and the Mojang guys though... they built a multi-billion-dollar empire out of nothing. It's real indie-games success story. An inspiration to the rest of us! Congrats!
