I could be reading it wrong, but it appears that from this interview with Eckstein, there "may" be more of Ahsoka in the future: Source I highlighted that sentence because it just sounds like "scenes with them" translates to other scenes with other characters. Granted it could be an elaborate P.R. way of talking because TWC might be canceled, or she's out of a job, but it sounds like Ahsoka will be back (just not with the usual cast of Anakin, Obi-wan and the Clones). Also she hints at this scene was recorded almost a year ago. Even though she may have other gigs, my assumption is she was recording new Season 6 episodes. Then again I may be all wrong and I'm just hoping she returns.
