A friend of mine let me know that the guys who leaked news of The Bad Batch - Kessel Run Transmissions and Jordan Maison - have also leaked the following:
- Ventress will get a limited animated series to wrap up her arc
- animated sequel show for Star Wars Rebels set the same time as The Mandalorian
- Barriss Offee will make a return, probably in TBB
- Sabine Wren is in The Mandalorian
I haven’t looked into these myself but they sound exciting. Given other rumours, it sounds like poor Mando will have a very busy season 2 meeting lots of major characters!
