Feels like maybe there won't be a S4. They might pick up on Mandalore a bit with Sabine in Ahsoka and then maybe it isn't until this Filoni movie that we see Mando return, hunting down Imperials.
"lol" though @ Moff Gideon seeing that "The Mandalorian has escaped" and even have tracking on him on a map somehow.... but then sending no one after him and just letting him come.... I forget if that scene was before or after Mando destroyed his clones.... if it was after then it is even more "lol" because presumably he would see Mando approaching his super important lab and do nothing about it and send no one to try to stop him... and then be super mad about it.
