Echoing what has been said prior, I am of the same mind that Han and Qi-Ra will be in the finale. Qi-Ra, as the post credits with Cad reporting the events. I do not think Season 3 is going to touch on Mandalore. In-fact, I am willing to bet Season 3 is going to focus on the Pykes, the conflicts in other planets as Djinn is sent by Boba to scout the other Pyke strongholds. That would also allow them to set up for the sake of Ahsoka, Lando, and other DIsney+ SW projects. Especially with Bo-Katan rumored to get her own show (And one that I hope is led by BDH), Mandalore should not be the priority.
