The @warcraft twitter account has been posting a few carefully taken pictures of something the past couple days, and today it's been reveled what the object is -- a Pandaren Brewmaster Figure that you can buy from the Blizzard store. The little guy is "on sale" for $50, and there are limited quantities available. Everything is first come, first serve, so if you want one I suggest getting getting it quickly.
The figure is of Chen Stormstout, who left his Pandaren home world to find better ingredients to make his brew with. These figures are usually of pretty high quality, and by the looks of it this one is exceptionally detailed. It's also not a small figure. It's over 8 inches tall and 4 pounds in weight, which makes it quite a nice desk statue.
Should be a good collectable for this who want it!
