There’s still no official premiere date for it, but Nickelodeon’s official YouTube page has revealed the first trailer for The Legend of Korra: Book III. Fans may be a bit disappointed that the preview literally reveals nothing about the next season’s plot, but should be happy about what is possibly a blink-and-you’ll-miss-it shot of fan favorite character Zuko. The Legend of Korra: Book II comes to DVD and Blu-Ray in July.
