Just in case we weren't completely sure of it yet, Activision Blizzard confirmed in today's quarterly earnings call that World of Warcraft: Cataclysm will be released in 2010. For general Blizzard fans, another game was given a 2010 release date: StarCraft II, which will begin its beta phase within a month. As was pointed out during the conference call, it has been twelve years since Blizzard released two major titles in the same calendar year.
The Cataclysm news is in line with everything we've heard so far, including Mike Morhaime's comments during BlizzCon that the expansion has a targeted release date of 2010. Things seem to be moving along right on schedule, but remember that this is Blizzard. Things could change at any time, so I wouldn't start preparing for leveling vacations yet. Actually, you probably shouldn't do that at all. It's kind of silly.
