Regardless of what the real numbers are, it is the most successul MMORPG to date. I was there for the launch of UO, EQ, DAoC and other less popular MMOGs and the sheer number of servers available for WoW boggles the mind. I think it will be a while before another MMORPG takes the belt away from the champ. And that's what'll be needed before this games dies.. something better. Many of these MMORPG people need to be playing or at least subscribing to one MMORPG game to get their fix. I doubt any of the up and coming games out there like D&D online will have the same mass appeal that this warcraft/blizzard title offers.
