The recent launch of World of Warcraft: Mists of Pandaria has given subscriptions a boost with Blizzard seeing 2.7 million copies sold in the first week. Total World of Warcraft subscribers have passed 10 million again in all regions. In August, Blizzard reported subscriptions for the game declined to 9.1 million. Last year at this time, subscriptions were at 11.4 million.

"It's been gratifying to see the results of all of the work we put into this expansion and to hear all of the positive feedback from players so far," said Blizzard CEO Mike Morhaime.

Blizzard said the World of Warcraft development team is already working on the first major post-launch content update.
