Popular World of Warcraft database site Wowhead has unveiled what it's claiming to be an official (and rather gigantic) Blizzard ad that reveals the official Wrath of the Lich King release date: Thursday, November 13. To celebrate, Wowhead is raffling off 10 beta keys. Though we know the expansion is due in Q4 2008, Blizzard has yet to confirm the date, either via press release or its website -- in other words, don't take this as gospel until we get an official statement. Update: The ad is now also appearing prominently on Thottbot, though it should be noted both it and Wowhead are owned by the same company. Update 2: Blizzard finally made it official (more official than a generous ad buy, at least). In other news, the Thanksgiving Day traditions of millions of families just got kicked in the sweetmeats.
