Screen Rant has the scoop. You can read it HERE. According to Screen Rant:
The Mandalorian season 2 casts Rosario Dawson as Ahsoka Tano.
They continue:
The character made her debut in the Clone Wars animated movie, voiced by Ashley Eckstein. While viewers didn't take too kindly to Anakin Skywalker's young Padawan at first, Ahsoka later evolved into a fan-favorite as the Clone Wars TV show progressed. She's now considered one of the more popular characters in the entire franchise...
Mmmmm. It's amazing what happens when characters have arcs (looks over his glasses at Rey).
Clerks 2, Daredevil and now The Mandalorian. Rosario Dawson has now joined Jon Favreau in inscrutable nerd-idol status.
