If it?s multiverse then the ST will exist but in a different timeline. However they will make a new timeline with grogu and new characters and bury the ST timeline. I just think the ST doesn?t sell enough to continue the brand so they won?t outright retcon it but they won?t acknowledge it anymore . Idk we will see
If they go Multiverse I think I'll still keep Mando 1 and 2 in my personal canon. It's just too much fun. And with Thrawn, Dark Troopers, and post-Sarlacc Fett it fulfills so much 90's goodness in live-action. Great stuff.
