Five years is a good run for any animated show, especially these days. I can't imagine the episodes still in the pipeline aren't going to air at some point. More than enough for syndication now.
Unless Ashoka went out in a blaze of glory, dying for a noble cause, no way were they going to kill her off. I've suspected for a long time they could have her simply missing in action, leaving open the door for her return in future projects. I'd like to see a Star Wars angle on marooned soldiers who don't know the war is long over.
Did the Sat AM timeslot hurt the ratings any last season? I thought they should have kept the Friday evening slot for reruns.
Detours should be put out of our misery though. ;)
Robot Chicken and MAD do more than enough spoofs, and are actually funny to boot.
