The last time we have had an update(September) on the digital version was months ago and Minecraft was at 8m on XBLA and I believe 12m on PC.
Since then Minecraft has sold another 1.5m on physical retail. It is very likely that XBLA is around 10m by this time as well and another 1-2m on PC if my numbers are right on the PC version.
This would put it above 25m all time not including the IOS version. Just think of how this game started off to what it is now. Congrats to Mojang and 2JStudios
