Yes, we do have something new coming out Korra related. The Korra: Making Of A Legend event which will run on Nicktoons for 12 days from Today July 9th to July 20th.

Korra Title final

What it is about is basically each day we will see 1 episode of Korra, a creator cut version, where Mike and Bryan will at times explain some of the background behind scenes. We do not know exactly how it will work and how long Mike and Bryan will talk for, but we should hopefully get some new insight into the episodes. It starts tonight at 9PM Eastern Time which is 8PM Central/ 2am on July 10th British and Irish time, 1am GMT. Here is the trailer from IGN http://ie.ign.com/videos/2012/06/22/korra-making-of-a-legend-promo PLEASE DO NOT POST LINKS TO VIEW THESE EPISODES IN THE COMMENTS OR ELSEWHERE ON THE SITE.  Just use google or pm people with links if you wish :)
