This is from NickandMore once again which like the episode titles from last week mean no source. They are reliable, so it more than likely means it is true, but don't take this as absolute confirmation.

They are reporting that Nick will premiere The Legend Of Korra Book 2 Spirits with the opening two episodes "Rebel Spirits" and "The Southern Lights" on September 13th and single new episodes will start the week after on September 20th.
For me this makes sense to do a 2 episode premiere especially given how long we have waited for Book 2.
Thoughts?
