Yesterday, Vivendi Universal’s Blizzard announced that its highly anticipated expansion for its best selling MMORPG World of Warcraft sold 2.4 million copies worldwide in the first 24 hours. The company had shipped 4 million copies to prepare for the demand. Traders considered this bullish news, buying up shares of World of Warcraft: The Burning Crusade, +3.00 DKP (+0.53%), which closed up 1.72% yesterday at 565.29 DKP (forecasts 5.65 million copies sold worldwide over lifetime). Shares had lingered in the 550 - 560 DKP price range for the past month as traders questioned how many players would purchase the expansion due to the relatively small portion of gamers who could actually make use of the expanded content.
