I don't expect to see it in the new movie because that's just not an aesthetic that seems in demand anymore in SciFi movies, but what I really miss from the original SW movies is the "believable dirt". That is, in stark contrast to say Star Trek, where every surface, every appliance looks like you just unboxed it, in the original SW movies everything was old, grimy and beaten up. And I loved that. It's a bummer they can't (or won't) reproduce that for the new movies.
