I think WoW is tweaking the numbers.
I suspect they are counting every subscription thats ever been registered and paid even a single 15$ month sub. to make the numbers seem huge.
I have no doubt that they have millions of active subs, but as an example,
Over the years I've had 3 accounts that I've played, but only one was active and able to log into a server at a time.
I'm going to assume that Blizzard counts all 3 in that 10 million because none of them have been suspended and *could* be paid for and played at any moment.
