We will be holding our next developer chat on Twitter on Friday, July 16, at 5:00 p.m. PDT with World of Warcraft's systems design team. This chat session will focus on the recently-announced talent specialization and Mastery system changes coming in Cataclysm: http://forums.worldofwarcraft.com/th...26290449&sid=1

We'll be taking questions live through Twitter, so be sure to sign up for a Twitter account at https://twitter.com/signup and follow @Warcraft to participate.

To submit a question for the developer chat, please tweet using the #BlizzChat hashtag between 5:00 p.m. and 6:00 p.m. PDT on July 16. Due to Twitter's character limitations, all answers will be posted in a dedicated thread on the World of Warcraft forums.
