I wonder how much his clone history is gonna be played up in this. The Mandolorian had Kuiil make a random reference to “strandcasts” (a term I’d never heard before Kuiil mentioned it, but apparently it’s a term for a kind of cloning done by the Sith/Empire/FO, which is how Snoke, Rey’s father, and Palpatine’s new body were created), then they had the Imperial clone experiments in The Mandalorian and Dr. Pershing with the Kamino symbol on his uniform, and then when Boba was introduced in The Mandolorean they brought up him being a clone pretty quickly. Also there’s the stuff with Omega and the Kaminoans happening in the Bad Batch.
It seems like they are building up the cloning side of things and slowly trying to fill out the very vaguely-defined clone backstory elements of Rise of Skywalker. And with Boba Fett being the franchise’s most famous clone, I wonder if this the show they’re gonna go more into that stuff with.
