GDC 07: WoW that's a LOT!

Officials from Blizzard Entertainment have just announced at the Game Developers Conference, that within just one month the World of Warcraft: Burning Crusade expansion pack has sold over 3.5 million copies worldwide! This grows the World of Warcraft fan-dom to an outstanding 8.5 million people! That's pretty good, especially considering it's only been a month since the release, and there's a handful of countries it hasn't been released in yet! WoW!
