In a recent interview with Blizzard EVP of product development, Frank Pearce, who is also in charge of the project, VG247 asked a question about the release date of Cataclysm at the end of the chat£º"But Cataclysm is set for release in 2010, so that should be out by the end of the year, yes?"

"Hopefully. If it's ready. If not, then we'll hold onto it. [Grins]." Frank Pearce said.
That is to say, the public date of Cataclysm has not been set in stone yet. This is not good news for millions of WoW players…oh wait, wait, isn't the number of the guys hovering around the Azeroth 11.5 million? YES, it is! But the remaining WoWers located in Mainland China are still playing The Burning Crusade there and waiting for the approval of Wrath of the Lich King from the appropriate agencies. So these guys obviously don't care about Cataclysm, they just wanna The Wrath of the Lich King.
