Today, while zooming the Avatar wiki, I found something very interesting:

Avatar: Legend of Korra (working title) is an upcoming television series set in the Avatar universe. The title was trademarked by Nickelodeon in May 2010 and leaked by the media shortly afterward; more information was revealed in late June 2010, just prior to the release of the feature film The Last Airbender.

Nickelodeon is currently staffing up for production, adding that Avatar: The Last Airbender co-creators Michael Dante DiMartino and Bryan Konietzko are involved and that more information will be forthcoming at a later date, possibly Comic-Con 2010. On July 21, the Associated Press confirmed the series for a 2011 release.

Specifically here.

I know I am excited . How about you?
