Mandalorian season 3 hasn't started filming yet, so it probably won't arrive until late 2022.
The Book of Boba Fett will be the next live action season to hit, which will be December 2021. It is a potential ongoing series, meaning if it does well they will order more seasons like Mandalorian.
The anime anthology Visions will still hit in 2021 as well. It will consist of 10 unrelated short films from various creators.
The Obi-Wan limited series is filming now, with Deborah Chow (who directed two episodes of Mandalorian) as the showrunner. It should drop in the middle of 2022 and will have 6 episodes. The Cassian Andor limited series should finish production sometime in the next month or so and debut in early 2022, with 12 episodes.
Not yet started filming:
Ahsoka (limited)
Lando (limited)
The Acolyte (potential ongoing)
New Republic Rangers (potential ongoing)
