"We appreciate the enthusiasm surrounding World of Warcraft: The Burning Crusade, and we're excited about putting the finishing touches on all of the new content," said Mike Morhaime, president and cofounder of Blizzard Entertainment. "We feel confident that the extra time spent polishing the game will result in the high-quality experience that our players expect and deserve."
Blizzard began the closed-beta phase of testing on World of Warcraft: The Burning Crusade earlier this month. The January 2007 release window will allow extra time for current beta testers to participate in the final stages of development and continue providing valuable feedback.
Further information on specific worldwide release dates, pricing, and other details will be announced in the near future.
