I'm curious if they're going to alter the Bad Batch arc to some degree to somehow slide in the whole "Rex, Wolfe & Gregor removed their chips" plot point from Rebels.
I mean one assumes that has to happen *before* Order 66, no? Of course that would mean Gregor would need to be re-introduced...so maybe he'll be the one the Techno-Union has instead of Echo? Would explain how he got so loopy in Rebels, though since he doesn't have the same history with Rex & Anakin that Echo did it would make the reveal a little less impactful.
I mean we already know for a fact that they are for sure altering Ahsoka's walkabout episodes, presumably to more organically integrate with the Mandalore arc, and one assumes to cut out the "deep beneath the temple" episode (though I hope not.) So there's a precedent.
