All good things must come to an end. Star Wars will be continuing on in some form or another for probably longer than any of us will be alive, but a beloved chapter of the Star Wars universe is about to come to a close. It was announced today that, after four seasons, Star Wars Rebels will conclude.

The big reveal was made during the Star Wars Rebels season 4 panel at Star Wars Celebration by Executive Producer and creator Dave Filoni. It was a very bittersweet moment for him and everyone in the crowd during the panel. Star Wars Rebels has been an excellent series for the three seasons it has been on so far, but this is a show that always had an end point. Since the series takes place between the events of Star Wars: Revenge of the Sith and Star Wars: A New Hope, there were only so many stories to be told in Star Wars Rebels before that clock ran out. The show is bumping up pretty closely to the events of Rogue One: A Star Wars Story and we can pretty safely assume we will be very close to that movie, or maybe even in it, by the time Star Wars Rebels season 4 finishes up. Here is what Dave Filoni had to say during the announcement.

"I really appreciate that love from you guys. I think I can make this story as meaningful as can be. I know what it's like when I don't get to end a series."

Star Wars Rebels season 1 takes place roughly five years before the events of Star Wars: A New Hope, so four seasons seems like a very logical amount, since the idea is to bridge the gap between the end of the Star Wars prequels and the beginning of the original trilogy. Dave Filoni has made some great contributions to the Star Wars universe, starting with Star Wars: The Clone Wars. But, as he points out, that show didn't get to end in a proper way. That is why he made a conscious choice to wrap up Star Wars Rebels in his way and give it a proper conclusion. He did not confirm, however, if a new Disney XD Star Wars series is on the way soon though.

Dave Filoni remained tight-lipped about specific story points in Star Wars Rebels Season 4, as he will surely want everything in this current Star Wars TV series to be a surprise. But he did drop a few juicy details. Both Mon Mothma, as voiced by Genevieve O'Reilly and Saw Gerrera, as voiced by Forest Whitaker, will be coming back in the upcoming season. It was also announced that Warwick Davis, who played Wicket the Ewok, among others in the Star Wars movies, will be playing Rukh, who was a character from the Heir to the Empire novel and is associated closely to Grand Admiral Thrawn.

We still don't have a specific premiere date for Star Wars Rebels season 4, but it will be debuting this fall on Disney XD. The voice cast for Star Wars Rebels includes Taylor Gray as Ezra Bridger, Freddie Prinze Jr. as Kanan Jarrus, Vanessa Marshall as Hera Syndulla, Steve Blum as Zeb Orrelios, and Tiya Sircar as Sabine Wren and is Executive Produced by Dave Filoni and Simon Kinberg. Also, in case you missed it, the first trailer for Star Wars Rebels season 4 was released, which you can check out for yourself below.
