The WoW Armory has received a pretty significant update today. The Armory now features a 3D model viewer, replete with robust features such as a fullscreen mode with quality options, background selection, and the ability to view your character performing a variety of emotes and animations. Your interactive character model can even be embedded on your favorite social networking site or guild site forums!
You can also use the Armory to bring Steam style activity-tracking to your game with the introduction of the Armory's new calendar and and character feeds.
The second WoW Twitter Devchat was also announced today, which is scheduled for tomorrow at 5PM PST, and will focus on Patch 3.3: Fall of the Lich King.
