I have to admit that I am very excited for Star Wars Rebels. We get to jump into the world a few years before A New Hope. The sense I get is that the old Star Wars RPG is coming to life. I've heard some comments about the inclusion of Jedi and I have to think back to cracking that West End Games book and finding Jedi character templates. Isn't Luke supposed to be alone? Well, not necessarily.
Kenobi and Yoda changed the beacon message at the Jedi Temple to warn the Jedi away. They have no idea who may have survived. Darth Vader evidently hunted down those he could find, but we know he didn't find Kenobi or Yoda, two of the Jedi he knew best. Plus we already know that some Jedi have left the order, including Ahsoka Tano. That leaves a surprising number of Jedi or partially trained Jedi who could have survived. So including someone like that in Rebels is not so outlandish.
It seems we are going to get to see at least 5 characters we already know reappear. Kenobi will appear in the form of the message he recorded in the Jedi Temple, Bail Organa, R2-D2, and C-3PO will appear in person in guest roles and Luminara Unduli appears on a surveillance tape. Who else may appear in the course of the series is anyone's guess.
Rebels promises to give us the state of things before A New Hope and a taste of what Star Wars fans everywhere have been dying for. Just the teases I've seen so far have me excited for the possibilities. I hope it delivers. There is a good chance with some of the team from Clone wars back.
