Wow. I wasnt expecting a live action Ahsoka.
well maybe, maybe not...
deadline says rosario dawson isn't a series regular although she appears to be in it.. also according to deadline, ahsoka being in season 2 is fan fiction...

but i am just gonna wait until season 2 of the mandalorian is available so i can find out one way or the other..
YMMV: Slashfilm is saying that Katee Sackhoff has been cast in season 2 as the same character she voiced already, Bo-Katan.
