It's already out. The whole series is done.
There was no Book 4, so no DVD can be released. The Last Airbender TV series ended with Book 3, but the story continued in a comic-book series 'Avatar: The Last Airbender: The Promise'. A spin-off TV series set in the same universe but many decades after the events of The Last Airbender called 'The Legend of Korra' is ongoing.
The movie "The Last Airbender" directed and produced by M. Night Shymalan is the closest you can get to a spin-off. It does not resemble the original series as much as the Avatar: The Last Airbender fans wanted it to.
