There is a ton of misinformation going around (Not in this thread yet, but in the Reddit thread and the YouTube comments) so I'm gonna try to clear some things up.
Future languages aren't coming in the way that a lot of people think they are. Duolingo is going to give users the ability to create courses for any language they want. They are no longer creating courses for new languages internally. That was confirmed in the latest AMA from a few months ago. "So that’s the approach we plan to take: Instead of us slowly adding languages, we’ll create all the tools necessary for the community to build them."
While no ETA was given in that AMA, Duolingo has recently announced that "Something big is coming to Duolingo." https://www.facebook.com/photo.php?fbid=617459704964869& on October 9th of this year. Taking the above information into account, it's pretty obvious what that something is. Course creation tools.
Also note that October 9th is Hangul Day http://en.wikipedia.org/wiki/Hangul_Day in South Korea. I don't think it means Korean is being developed internally and will be released on that day, but it's still interesting.
