According to Ahsoka....she is no longer a "Jedi" during the "Dark Times", which is the timeline Rebels and the OT takes place....so the title is pretty inconsequential in terms of more Force-wielder action in future Star Wars post Episode 9....TFA and Rogue One also pretty much made that clear......
At this point, I'm more interested in how Rebels will play out.....heck, even Maul is no longer a Sith....will they kill off Kanan, Ezra, and Ahsoka.....or keep things interesting?.....
