Three different series will culminate in a climactic event. I’m thinking the Ahsoka series will primarily deal with her and Sabine looking for Ezra by finding Thrawn. Season 3 of The Mandalorian probably focuses on Mandalore and the darksaber. No idea what Rangers of the New Republic could be. I like Ezra, but even if you don’t, I doubt he’s coming to take over all three series. I do think the beginnings of The First order could be involved though, but that’s just a guess.

Side note, my two cats are named Ezra and Sabine.
