Usually I prefer official sources, namely Blizzard. Gamespot reports the Vivendi Quaterly Report confirms Wrath of the Lich King is scheduled for release on the second half of 2008—which is anywhere between July-December range. Most likely November-December. However, Vivendi has no say on release dates. Only Blizzard can call that shot. It is out when it is ready. Read more at Gamespot.

Today, speculation yielded to confirmation. As part of its quarterly earnings report, Vivendi SA, the French multinational that owns Blizzard Entertainment, officially announced that Wrath of the Lich King “is scheduled to be released in the second half of 2008.” Given that the first WOW expansion, The Burning Crusade, sold 2.4 million copies in just 24 hours, the add-on has the potential to dominate the PC gaming market during the holiday quarter.
