"Star Wars Rebels" will come to an end after the upcoming season. This was announced by show creator Dave Filoni during the show's panel at the Star Wars Celebration in Orlando, Florida.

"This is where I have to tell you that Season 4 is the final season of 'Star Wars Rebels,'" he said, adding that he wants the show to end on a high note, in a place where he was satisfied with. Fans have taken this statement to mean that he was referring to the premature cancellation of "Star Wars: The Clone Wars" after its fifth season when Disney bought Lucasfilm. The animated show was eventually picked up by Netflix.

He also said during the event, "Seeing the evolution of this family, [and] these kids, and watching them get older, as a creator of a story I think of these things. I think about where we are going, and what the characters need to go through."

While "Star Wars Rebels" is set to end, it does not necessarily mean the end of the story for the show's characters. For instance, Sabine and Ahsoka have already been revealed to be the protagonists for the upcoming animated series, "Star Wars: Forces of Destiny."

Filoni described season 4 of "Star Wars Rebels" to be "different, a little dark, a little fun."

The trailer of the fourth and final season of "Star Wars Rebels" premiered during the event. It served somewhat as a montage of protagonist Ezra's journey throughout the show's story. However, it also teased at upcoming events, such as the appearance of Imperial hover tanks, which first appeared in "Rogue One: A Star Wars Story." The panel revealed that the last season will tie into the story of the aforementioned film.

The trailer also showed Bo-Katan Kryze from "Star Wars: The Clone Wars," as well as Grand Admiral Thrawn. Aside from Ezra, Saw Guerrera and Mon Mothma will also be returning for the final season. Meanwhile, Warwick Davis will be joining the cast, voicing Rukh, Grand Admiral Thrawn's bodyguard.

Season 4 of "Star Wars Rebels" will have 15 episodes.
