There making a new avatar series.

Avatar: Legend of Korra takes place 70 years after Avatar: The Last Airbender. Korra is the next Avatar after Aang, "a passionate, rebellious, and fearless teenaged girl" who is hotheaded, independent and "ready to take on the world". Korra comes from the Southern Water Tribe, and Aang and Katara's son Tenzin is her Airbending teacher.

One of the story's settings is Republic City, a "metropolis powered by steampunk-type technology," "inhabited by people from all nations." Here Korra must deal with rampant crime and an anti-bender revolt.

Although the creators of the show had planned an ending to the show, the success of Avatar: The Last Airbender caused Nickelodeon to ask for more episodes. The creators then came out with this new idea of the next Avatar, this time a girl named Korra. They decided upon a female Avatar after the large audience of females of the original show, and felt it was time to have a big action franchise with a female in the lead instead of the traditional male role.

The show will be darker and more mature than the original show, with more mature themes, but will also try to balance it out with a similar sense of fun and adventure of the original series.

Sounds great, i can't wait
