Diablo 3 expansion planned, as game sells over 10 million

Diablo 3 is "the top-selling game overall" based on digital and retail sales in North America and Europe, Activision has proudly proclaimed. The long-awaited dungeon crawler has sold "in excess of 10 million copies," CEO Bobby Kotick said in a recent earnings call.

Of course, there''s much more money to milk out of the Diablo franchise. Blizzard confirmed that "we do have an expansion planned" for the game, but there's currently no timeline set. Citing Blizzard's high quality standards, it could be quite some time before we actually hear anything else on the subject.
