Now that all previous media related to Lucasfilm (Lucasarts, ILM, and Lucasfilm Animation) have had all their projects and assets cancelled, sold to third parties, delayed indefinitely, and/or otherwise "resolved", Disney has announced its intentions for the future of the franchise. Most of the material, if not all future media (at least for now), will be sequel trilogy focused.
One of these projects appears to be a cg animated post-Rebellion era series similar in layout to the Clone Wars, and will also feature iconic characters from the OT. It will see our heroes and their allies in the Rebellion as they hunt down the remnants of the Empire in events directly following the destruction of the second Deathstar, and may foreshadow the events in the sequels.
Okay, so no Papa Palpatine. No Vader. So are all the villains going to just be Imperial officers? Sure, Thrawn was cool, but if his back was against the wall he didn't possess the means to stand up to a fully-trained and armed Jedi Knight, though he would have most likely died trying. Next we have the delicate issue of just which characters will be in the series. Luke, Han, Leia, Chewbacca, Lando, Mon Mothma, Admiral Ackbar, and Wedge will likely make up the mainstay of the cast, but also to consider are other honorable mentions like Garm bel Iblis, Boba Fett, Rahm Kota, Starkiller, Maris Brood, Kyle Katarn (my pick ;)), Jan Orrs, and the RotJ ghost-Jedi trio. Less likely to appear (but possible) are Ahsoka, Ventress, Maul, clone-Palps, and any surviving recurring clone character from CW.
