OMG: “The Legend of Korra: Book 3” Official Trailer
This looks insane, I can’t wait for its release date.
Zuko! I wonder if that’s a flashback or the present.
The wiki entry mentions that during post-production episodes three through six (dubbed in Spanish) were accidentally published on the website of Nickelodeon’s Mexican affiliate MundoNick, from where they became available elsewhere on the Internet, but I honestly would rather wait for the ones in English, especially because I don’t know how much story is missing without those two first episodes.
