2.8 million sign on for more World of Warcraft in 24 hours

At a clip that the company says makes it "the fastest-selling PC game of all time," and clearly showing no signs of slowing down in the nearly four years since its original release, publishing juggernaut Activision Blizzard says World of Warcraft's second expansion, Wrath of the Lich King has sold more than 2.8 million copies in its first 24 hours, eclipsing January 2007's Burning Crusade expansion record of 2.4 million copies in the same time.
