i just read on wikipedia that the writers are thinking about continuing after the third season with a new avatar and such. this is what i read and is directly from the page.

Michael Dante DiMartino and Bryan Konietzko have also confirmed that a new series of Avatar, focusing on another incarnation of the character, is in the process of being made.

this is really big news and i (as i am sure all of you are) exicited for. and let us not forget the live action movie that is in the works.

On January 8, 2007, Paramount Pictures' MTV Films and Nickelodeon Movies announced that they have signed M. Night Shyamalan to write, direct and produce a trilogy of live-action films based on the series; the first of these films will encompass the main characters' adventures in Book One.[ The film was in a dispute with James Cameron's film Avatar regarding title ownership, which resulted in the film being titled The Last Airbender. It is set for release on July 2, 2010. Filming will begin in Philadelphia in May 2009, and it will be shot in Greenland.

Avatar co-creators Mike DiMartino and Bryan Konietzko have come forward to voice their opinion within an interview regarding M. Night Shyamalan writing, directing and producing the film. The two displayed much enthusiasm over Shyamalan's decision for the adaptation, stating that they admire his work and, in turn, he respects their material

now i have no idea when this stuff will happen or come out, but what i do know is that avatar is not yet over
