According to a variety of sources, Blizzard's MMO has actually gained about 200,000 subscribers since the end of last year. Blizzard's 2013 Q3 earnings call reported 7.6 million subscribers and now the recent 2013 Q4 earnings call has reported a bump up to 7.8 million subscribers.
World of Warcraft has been well populated for the past 13 years (launch was in November of 2004) and it has survived many so-called WoW-killers. Will any of the new 2014 MMOs finally usurp WoW's throne? Will it be WildStar? The Elder Scrolls Online? EverQuest Next or EQN Landmark? In this fickle, high-risk industry that kills off most MMOs in 2-3 years, WoW has become exceptionally good at not dying.
