World of Warcraft fans had better get ready, as news comes from our sources that Blizzard is accepting signups for the beta of World of Warcraft: Cataclysm until April 15th. Prior to April 15th, members of the media will get a preview. While signups will end on April 15th, the beta will not go live on that date.

Cataclysm is being billed by those who claim to know as the most significant changes to Warcraft since release. While Blizzard has not made a formal announcement yet, we expect them to do soon in the next week or so, according to our sources. Also, Blizzard (as is customary) has not announced a hard release date for Cataclysm yet, and we don’t expect them to do so until they are much closer to release.
