I hope there will be a next season. I want to see everyone else is kids and what will happen next with Korra and Mako and possibility Zuko's kid General Iroh.

There is already another season in the works. There will be 14 episodes and the "Book" is called Spirit.

*General Iroh is Zuko's grandson* but they do have the same voice actor.

yes there is a new season and iroh is not zuko's son

Iroh is not zu-zu's kid thats his grankid but they share the same voice actor
