UPDATE: The news is now being confirmed by multiple sources, so it looks like this is happening.
While I would keep this in the rumor pile until we get additional confirmation,
/Flim is reporting that actress
Rosario Dawson (Daredevil) will be taking up the role of
Jedi Ahsoka Tano in the second season of the
Disney+ Mandalorian series. Up until now Ahsoka is a character that has only appeared in animated form. The character was originally created for the Clone Wars animated series to be Anakin's Padawan. We have seen the fan-favorite character grow over the years and survive the great Jedi purge after the events depicted in Revenge of the Sith. An older version of the character was last seen in the Star Wars Rebels animated series which took place right before A New Hope.
