The airdate for the first episode of Book 3 of "Avatar: The Last Airbender" was officially announced at Comic-Con. It all starts September 21, 2007!

Also, saw at Amazon that they already have the first DVD of Book 3 available for pre-order. It's scheduled for release on October 30, and yes, it has that cover artwork I mentioned a couple of weeks ago.
