Diablo III has become the fastest selling PC game of all-time with 10M units sold. The game had sold 6.3M in its first week, with 3.5M .
(Of those 3.5M, 1.2M of them were World of Warcraft annual pass holders, who received the game free.)
In the call, Activision also revealed Skylanders: Spyro's Adventure was the top selling videogame of 2012 if one counts the collectible figurines that functioned as physical DLC. The publisher expressed optimism that the upcoming Skylanders Giants would be equally successful.
Not all of the news was bright, however. In the past three quarters, World of Warcraft lost over a million subscribers; its paid subscribership stands at 9.1M. The publisher hopes that Mists of Pandaria will attract new and former subscribers to the venerable MMO.
