Hi My fellow avatar lovers the series may not be over just yet. As many though after watching the latest avatar movie .there is much more in planning i found a website that stated that nickelodeon had another season planned for the book of air . Season four and also a movie is the works for the avatar spin off sequel .Also the new look for the avatar may be a female sadly aang will be no more but there will be some super star camios some being miley cyrus and samuel L jackson .surely Avatar the Last air bender on the big screen will be a big hit.
