The Mandalorian Season 4 is difficult to guess what would happen without a trailer.
Ahsoka Season 2 would be nice, to see how Thrawn returns. I have a theory that Thrawn will die, as in Legends he died the same time period.
Andor Season 2 would probably tell us how Cassian joined the Rebellion, would be pretty nice.
The Acolyte's trailer slightly disappointed me. Just didn't feel like Star Wars honestly. I'm probably to used to the Galactic Empire rather than High Republic etc. I'd only enjoy it if Tarre Vizsla was mentioned and we could learn more about him.
Squadrons, I don't have anything to say about to be honest.
