I was just listening to the Activision Blizzard Fourth Quarter Calendar 2009 Results Conference Call, to see if anything about SC2 was released(which beta will be out this month.) During the call, Mike Morhaime announced a couple interesting wow tidbits. The first is that the auction house will become availiable out side the game, through the web, and even mobile devices. Some of these services will be free, others he refered to as "premium."

The next was the mentioning of a couple new pets added to the blizzard store, that will come with a real-life plushie version of the pet.

Then the recording of the conference call is up, I will link to it. Also, as if anyone didn't know... Cataclysm is still set for 2010 release.
