Secondly we have an interesting interview with Mike, Bryan and Gene Yang.
The big news to take out of this is three things
-Bryan off handedly confirms that there are two animation studios working on Korra, this was not mentioned during the panel, but has been speculated by fans for months now. So Pierrot Co. are confirmed to be working on Korra also, they animate episode 1 of Book 2. -Lin is confirmed to have only a very small role in Book 2, but will have a bigger part in Book 3 and 4. The reason is that Book 2 is not very republic city focused and Lin is a character who is focused on the city. -Possibly most interesting of all Gene Yang in reference to this mentioned that we will be seeing a lot more of Toph in the upcoming comics. Now as far as we know now, the only announced comic that is not yet out is The Search Part 3 and Toph is more or less confirmed to not be in it especially in a big way. So I think Gene basically confirmed a 3rd comic series that will focus on Toph. At the very least more comics.
