Wouldn't be surprised at all to see them pop in for an episode. I wouldn't want them to take over completely like they did on Boba Fett (those were the best episodes of the season but still) but I'd very much like an appearance.
While I'm always happy to see Din and Grogu show up, I'd actually rather see some other faces. Haven't heard anything about Rex being on the show but I'd like to see him. I'll be legit pissed if we don't get any more Luke, and it'd be nice to see someone else from the OT as well.
And I won't be surprised if Skeleton Crew gets teased/setup on Ahsoka either.
I wonder if the movie getting approved is the reason for this? If they're doing an Heir to the Empire story for the film then clones are gonna be a big part of it, and maybe plans for Gideon had to be changed. Or maybe this was always the plan for Gideon, it all lines up neatly enough. And it was always an assumption on our part that Gideon was part of Palpatine's cloning project.
Personally I like what we got. Seems Gideon's super soldier program wasn't part of any "official" Imperial plans, and given the tensions in the Shadow Council I get the feeling Gideon was creating those clones to use against his allies in a bid for power as much as he planned on using them against the Republic. That could make for some good drama, assuming Gideon's story gets to continue.
