"The Last Airbender: Legend of Korra" is due out on Nickelodeon in mid-2012.
Originally, the new series had been picked up for 12 episodes, but Nickelodeon recently ordered 14 more.
The creators say they "have lots of ideas for the Avatar universe" and that they "could be tapping into them for years to come".
The present status of the new series: all the scripts have been recorded and the episodes are currently being animated.
The tone of the new series is older. The main characters are in their late teens, with Korra herself being 16 or 17.
Ships ahoy! "We've always loved those kind of teen love triangle type stories [
] We're definitely getting into it in this series."
There will be cars and motorcycles in the world of Avatar Korra.
Regarding the characters from the original series, Bryan says "it's 70 years later so they'll appear in various ways perhaps", and Mike adds that "there is definitely a link to the old series and the old characters."
Korra's personality is basically the anti-Aang. She is "in your face", "tough", "headstrong", and sometimes picks fights with people on purpose.
The main villain of the new series is "kind of an anti-bending revolutionary guy", who is also described as "very scary" and "a challenge for Korra".
The mystery of Zuko's mom continues. Say the creators, "That question will be answered in some way, but not necessarily in the show."
