No its not. Even with 5m, heck even with 2m subscribers its an awesome business case. And even in 5 years, no 10 years we still can play WoW. Wanna bet?
Simply because until today no successful MMO has been shut down. You still can play Ultima Online or even Tibia if you want, both like 15 years old?
