From http://tvbythenumbers.zap2it.com/2012/06/18/season-1-book-1-finale-of-nickelodeons-hit-animated-adventure-series-the-legend-of-korra-premieres-saturday-june-23/138594/

We have information on what Korra we have to expect after the finale.

What that is is that Nicktoons will be airing the episodes with commentary from Mike and Bryan

further explained in the article

“After the finale, The Legend of Korra fans can learn more about the mythology and creation of this franchise by tuning into the Nicktoons’ “Korra: Making of a Legend” special event from July 9 – July 20 during which all twelve episodes from Season 1, Book 1 will air weekdays at 9:00 p.m. (ET/PT). Each “creators cut” episode offers insight into the creation of the stunning imagery, mythology and storyline where series creators and executive producers, Michael Dante DiMartino and Bryan Konietzko, provide commentary.”

So this may give us some great insight into the episodes, I am excited, though I really hope these are put up on Nick.com as otherwise these are going to be difficult to see if you are not in america.
