After that there are a series of Graphic Novels that are set after the events of Season 3 that will continue the Avatar storyline, these will come early 2012. Here is a summary of the news:

On May 7th Two introductory stories from Avatar The Last Airbender will be released.
July 13th will be when the 240 page comic book "The Lost Adventures" will be released, said to be similar to the Comics released in the late Nickelodeon Magazines, and a "continuation" of them.
Early 2012 will be when the Graphic Novels set after events of Season 3 will be released and "will follow the further adventures of Aang and his friends, as they help to rebuild a world torn apart by 100 years of war." This one should answer the questions about Zukos Mom, Azula, Romance, etc..

So looks like Avatar Series Creators want to get the loose ends of Avatar The Last Airbender tied up in comic book form, which should free up some more time in Avatar The Legend of Korra for the Korra storyline.

Avatar The Last Airbender the Art of The Animated Series was incredible, so I have high hopes for these new stories in the Avatar The Last Airbender Continuity!" And looks like the loose ends of Avatar The Last Airbender will probably be tied up at last!
