" Hey Korra Nation! Phew. Some of you may have heard versions of this news elsewhere, but here’s the official word. After this Friday’s on-air premiere of Episode 8 “The Terror Within” at 8/7c, all remaining Book 3 episodes will move to a digital rollout. That means two things: 1) Korra is NOT cancelled, 2) the remaining episodes will roll out weekly on Nick.com and the Nick app beginning August 1, as well as on platforms like Amazon, Google Play, Xbox and Hulu.
Thousands of you have been asking to watch this incredible show online, so hopefully this news works in your favor. Mike and Bryan created a breath-taking season for us all…so get ready to watch it all go down!!!
Thanks for being the BEST fans in the industry and see you at Comic-Con." - KorraNation Tumblr
