With Filoni and Favreau I wouldn’t put it past them to create an alternate timeline using Ashoka and the world between worlds.
They seem to be hinting at it with the Ashoka series cover.That way you have a clean slate post ROTJ, while keeping The ST confined to it’s own timeline.
Have your cake, and eat it too.
I will eat an Ahsoka action figure if this ever happens. I see so many crackpot theories about how the Sequel Trilogy is going to get decanonised - I would’ve thought that people would’ve moved past the denial stage by now (or is this bargaining?). Disney wouldn’t do that to the movies they just spent millions on, and which have been seen by so many people.
The worst that’ll happen to the ST is they’ll be slowly eroded away at through the power of recontextualisation, much as about half of the dialogue in Star Wars 1977 now has to be explained as “Obi-Wan was lying!” or “Obi-Wan was just calling him Darth to tease him!” etc. It sounds like the upcoming Obi-Wan series will prompt another few lines in the OT to suddenly need to have their commonly understood meanings adjusted.
New stories always find their way into the gaps and create new interpretations of events. Back in 2005, Anakin didn’t resent the council for accusing his Padawan of being a terrorist, and the Clones didn’t have biochips in their heads. In 1983, Vader wasn’t the prophesied Chosen One bringing balance to the Force, he was just a protective Dad. This website understands this better than most Star Wars communities.
