Funny that, I just finished Season 5 - as in the last few episodes, for the second time. So sad.
And yes unfortunately she only has a tiny quasi-cameo in Season 6 not really worth talking about. But I'm sure she'll appear again the future, whether that be in the movies, Rebels or one of the upcoming novels, it will happen
I would be ecstatic to see Ahsoka show up in either Rebels
or Ep. 7, but I think I'd prefer her in an animated context so that she can be voiced by the same actress who voiced her in TCW. But really, I just want to see more Ahsoka Tano in Star Wars!
