Blizzard's had their Q4 earnings call, in which all of their most important moneymen hop on the telephone to gossip about the business of orcs. During it they announced that World of Warcraft subscriber numbers were at 10+ million at the end of 2014, a two-year high for the flagging MMO.
The number represents a spike of 2.6 million subscriptions around the launch of the most recent expansion, Warlords of Draenor. That's the largest jump in subs World of Warcraft has seen around such a launch.
At its peak, before the launch of Cataclysm, World of Warcraft enjoyed an industry dwarfing 12 million subscribers. That number has fallen as low as 6.8 million during the summer of last year, before sproinging up again in the Warlords of Draenor madness.
Typically however, subscriber numbers taper off again after Blizzard drop an expansion on us, with the publisher expecting to have seen chunky declines in Asia since the end of 2014. Next quarter's reported numbers will reflect just how well Blizzard have done in holding on to those subs.
The company also reported that Hearthstone has over 25 million registered players, while 9 million users have registered for the Heroes of the Storm beta.
