The trailer for "Star Wars Rebels" premiered during the "Star Wars Celebration" in Orlando, Florida. The cast also formed a panel to answer some questions about the fourth season of the animated series.

According to Slashfilm, Hera Syndulla will be promoted to General of the Rebel Alliance in season 4, which, incidentally, was already her designation in "Rogue One: A Star Wars Story." According to Vanessa Marshall, the character's voice actress, she will have sharper focus this season 4, and her motivation may very well be the losses that the team encountered in season 3. It is interesting to note that despite her promotion, she seems to be wielding a smaller aircraft than what she previously piloted.

Another plot point that season 4 will explore is Sabine Wren's Mandalorian family. The trailer also portrayed her handling a light saber. The Star Wars website teased that this could mean that she is learning to master the weapon, maybe using this more over the double blasters, which she was known for using in the past.

Meanwhile, Kanan seems to have adjusted to his blindness. In fact, he was described by his voice actor, Freddie Prinze Jr., to see more than he did before. He said, "He knows what path these Rebels need to be on. It takes some time to figure it out, but once he figures it out, he has the certainty that you've seen in other Jedi before."

Saw Guerrera, Bo-Katan, and Mon Mothma from "Star Wars: The Clone Wars" both make an appearance in the trailer, although it is still unclear what their roles will be in the series. However, Saw has been described as an extremist since the events of "Star Wars: The Clone Wars," which will have an impact on how the Rebel Alliance will deal with him.

"Star Wars Rebels" will end after its fourth season. Showrunner Dave Filoni thanked fans during the event, saying, "I really appreciate that love from you guys. I think I can make this story as meaningful as can be."
