I think this number is BS. Even if it were true - which I seriously doubt it is - I know for a fact that they're also losing a lot of customers. After 3 months (6 at the outside) there's absolutely no point in playing anymore. It's boring as stink. Not to mention the game consistently gets worse with each patch, the devs are inept and have zero concept of what class balance is about - partiuclarly as it applies to PvP. No real new content. And the list goes on. People will keep quitting this game in droves as well.
