Back in July it was reported that Nickelodeon was pulling the last 5 episodes of Legend of Korra: Book 3 “Change” from its schedule. It was also reported that they would be posting the final episodes online, so fans could finish off Book 3.
Now Nickelodeon is apparently going to air those 5 episodes on TV, but on Nicktoons. Book 3 starting with episode 1, will premiere on Nicktoons starting Monday, September 15th. With episodes airing Monday through Thursday nights at 8pm EST. Then the 5 episodes that were pulled from Nickelodeon will make their television debuts Monday, September 29th through Thursday, October 2nd with the finale airing as a one-hour special.
Along with the news of Legend of Korra: Book 3 heading back to television, news of the Blu-ray and DVD release has surfaced. On December 2nd, Nickelodeon will release Book 3 on Blu-ray and DVD, with both sets featuring 2-discs containing all 13 episodes. Extras will include Audio Commentaries by Creators and Crew (you’ll get 4 on the DVD set, and on Blu-ray they’ll be on all 13 episodes), as well as Behind-the-Scenes Featurettes with Animatics (again, 4 on DVD and 13 on Blu-ray).
