[Theory] Kaguya's Theory. Read that.

And the edo kages.

That's true, I forgot about them for a second, which reminds me actually... since they are all unaffected by the genjutsu likely because they are undead and you must have a living body and eyes to fall under, it's highly possible Tobirama and Hashirama can help undo some people under the spell, while the third and Minato can possibly help with that sealing scroll Tenten had found before the genjutsu took place.

I also wonder if Rikudo will make a long-awaited appearance in the living world to assist against his mother and or what may happen on the possible other world.

Very nice theory, very possible in fact. There has to be a reason she wants the zetsus, and since there would be nobody left on the planet to fight, it's quite possible she intends to do battle on another world, and if this all pans out the way I am thinking, Sasuke, Naruto, Obito, Kakashi, Sakura, and Madara will all be there for the ride.

Or they are already in the other dimension...
