There's some rumors/speculation that we might finally see a Han/Boba fight, using of course the same tricks used for Luke.
Indiana Jones V's filming seems to indicate we might see a de-aged Ford, so maybe it'll use similar technology? If Ford agrees to at least do the voice, I guess.
Eh ... Luke was fine, Han would be a bit much.
I'd rather see Boba brawl with Chewie if we're going to the OT well.
