We already know that the Korra SDCC Panel will be on Friday July 19th from 11:15am-12:15pm, but we were not sure who would be on the panel or what it would be about beyond it being called a Korra panel.

We now know who will be there and what it will be about.
Nickelodeon's The Legend Of Korra Returns! Executive producer and creator team Bryan Konietzko and Michael DiMartino (Avatar: The Last Airbender) and co-executive producer Joaquim Dos Santos (Avatar: The Last Airbender) discuss what's in store for the highly anticipated Book 2: Spirits. The mind-bending panel will be full of never-before-seen artwork and the ultimate of sneak peeks. You'll also get to hear from your favorite characters, as talented voice actors Janet Varney (voice of Korra), David Faustino (voice of Mako), and P. J. Byrne (voice of Bolin) share their experiences working on the series. Moderated by Bryan Konietzko.
Never before seen artwork, as expected, but awesome to see they will be showing more. The ultimate of sneak peaks, what on earth is the ultimate sneak peak, for me this would have to mean a large trailer or say all or half of episode 1 of Book 2. Either way this is the panel we have all been waiting for, this is where we expect to get a release date and now we know there will be a lot of Book 2 news. As of now we only have the Thursday and Friday schedule for the con, Saturday and Sunday's schedule should be out tomorrow and this Sunday. We do know that Mike and Bryan have stuff planned over more than 1 day, so there is more to come from this comic con. How excited are you for this panel ?
