Over 15 million copies of Diablo 3 have been sold

Activision Blizzard has announced that over 15 million copies of Diablo 3 have been sold. The news comes thanks to the company's latest financial report.

The report also stated that World of Warcraft ended 2013 with 7.8 million subscribers, where it continues to be one of the world's most popular subscription-based MMORPG's. Shifting back to Diablo, Activision Blizzard Bobby Kotick says that the high Diablo 3 sale numbers is great as we head closer to Diablo 3's first expansion, Reaper of Souls, which gets released next month.
