I expect that we’ll see some established characters be promoted to high-ranking positions within the Resistance. (I think it would be neat to have some OT characters make an appearance, but I have no clue if they would do that.) I also think it’s going to depend on how they deal with Leia’s arc, because obviously at the moment she is a very important Resistance leader. Since pretty much every other leader of the Resistance and the New Republic is dead now, it’ll probably end up being a rather small, close-knit sort of government, unless they decide to introduce a whole bunch of new characters, which would be a bit odd at this point. Seems to me that, first of all, Poe will get a pretty big promotion, and second, they’ll gather together the surviving leaders of both groups as they attempt to regroup.
