re: Avatar: The Legend of Korra Books 3 and 4 Thread (Book 4 premieres in October)

Here's some Book 4 News and Rumors
LINK
The most interesting ones

Book 4 will be 13 episodes long.

Given that Book 1 focused on Korra learning Airbending, Book 2 on the Water Tribes conflict, and Book 3 on the Earth Kindgom, it is likely Book 4 brings us to the Fire Nation and current Fire Lord, Zuko’s daughter.

Korra and Katara have a scene together.

Book 4 is rumored to have a January 2015 release based on the fact that this is when the Book 3 Artbook comes out, and the previous Artbooks have had releases timed approximately with the next season. Beyond this grasping-at-straws connection, January seems like a reasonable release time considering how far along production is and the fact that online distribution eliminates Nick’s scheduling issues.

Bryke have stated that 2014 was Korra’s last big SDCC panel, meaning that Book 4 will be released before summer of next year. This further supports the Q1 2015 rumor, as well as the likelihood of us getting our first look at Book 4 at NYCC this year, October 9th-12th.
