User blog comment:The Milkman/Dragonborn DLC coming to PS3 and PC/@comment-3428817-20121204190841/@comment-4057437-20121207004827

The figures were from statisticbrain.com. They said the numbers came from Bethesda, Timeoin. As for fault, we havn't pointed a finger at anyone, we are sure no one is blameless.

@ Anon - There is nothing saying the numbers were only from North America. (Care to provide us stoopid fools some documentation otherwise?)  As they included PC sales, which are often downloaded, you are most likely incorrect.

And yes, we play both PC and XBox. :-D
