So as improbable as this sounds, what if we could see some new factions in IX. Here's a few I've come up with:
—Supreme Leader Kylo Ren's FO: The First Order troops loyal to Kylo Ren, led by his Knights of Ren. This faction is supplemented by some form of Clone army and is based around Vader's Castle.
—Some sort of renegade First Order that hates Kylo Ren and plots his downfall
—The New Republic: the few planets that survive the invasions by the First Order are unified with the Resistance leadership, they wage a more conventional war against the First Order
—Some form of unified Scum and Villainy faction dedicated to keeping criminals free of both the First Order and the Republic.
—A non-First Order Imperial Remnant, perhaps the Empire of the Hand.
EDIT: And because no one's mentioning it, Bob Iger of Disney came out and said they're slowing down Star Wars movies. I have mixed feelings about his announcement. On the one hand he took responsibility for Star Wars failing, which is something we haven't seen before from Star Wars execs. On the other hand they're not making as many anthology films which were some of the better Star Wars films in my opinion. They certainly were our best chance at getting familiar characters and/or settings.
