World of Warcraft had 10.2 million subscribers in February and now it has 9.1 million. Blizzard have been quick to point out that their ageing behemoth is still the most popular subscription MMO in existence and also to reiterate the cyclical nature of peak subscriptions. They fell before Cataclysm and the fall before Pandaria was expected. It makes sense that people would drop out when they’ve experienced all the content on offer but MMOData.net’s tracking doesn’t show sub levels below 10 million since 2008, at which point growth had been continuous. While subs will most likely recover with the release of the pandas on Sept 25, the returns may continue to diminish. During the earning call there were words about Diablo III as well.
