1 million less people are playing World of Warcraft than last reported. The latest estimate of subscribers claimed by Activision Blizzard cites a number of 9.1 million—from financial results released today—down from the 10.2 million reported this past May.
This marks the first time that WoW's subscriber base has dipped below 10 million since January 2008. The recent subscriber peak for WoW was 12 million as of October 2010. Of course, the number may change once the Mists of Pandaria expansion comes out later this year.
