Blizzard have announced that World of Warcraft has hit 8 million subscribers. Even if you assume that a substantial amount of these are lapsed accounts this is still a hugely impressive figure. Of course, this announcement is perfectly timed, with Burning Crusade - the first expansion pack for the game - released next Tuesday, complete with midnight store-openings around Europe. I'll be interviewing one of WoW's designers on Monday afternoon, so post any Azeroth-related questions below and I'll get some answers.
