I don’t think the ones in charge of the movies do care that much of the tvseries. Ok, a minor TCW character will be a minor Rogue One character, but seriously who would think that a kid-oriented tvseries is going to show the premice of the Snoke character, hence destroying one of the subplots of Ep VIII ? I highly doubt they would do that (has Ryan Johnson written a season 3 episode ?). The show needs to focus on its own plots (including loose ends of TCW, such as Maul/Obi-Wan, Anakin/Ahsoka and so on), everything else they’ve tried to do wasn’t that great so far.
