Maybe the studio has enough manpower to work on two games? They are making a truly absurd amount of money from WoW (10 million subscribers at $15 per month generates revenues a little bit like putting out a game as successful as Bioshock or something every month!) and I'm sure the studio could afford to do just about anything at this point.
They don't make 10,000,000 x 15 tho, btw, because a lot of people take package deals, and some foreign countries (China etc) pay per hour, instead of month.
still pretty HIGH UP THERE though, but they probably spent tons of that money on their new FUCKING MANSION with EPIC BENEFITS such as SAND VOLLEYBALL COURT.
I *still* don't get that.
