Minecraft for Xbox Live Arcade has now surpassed 3 million units sold. The announcement comes via Twitter from Mojang's lord of the blocks, Markus "Notch" Persson, who wrote this morning: "I got told Minecraft for XBLA passed three million sales today!" The $20 downloadable title launched on May 7 and sold a million units in five days. It then reached two million sales in early June. Minecraft for XBLA has also enjoyed significant support through updates, the latest (v 1.73) having gone live last week.
