In the Aftermath books they have talked at length about Super Star Destroyers. There are three Executor Class Super Star Star Destroyers that are mentioned alot.
Executor - The one we all know and love.
Ravager - The one from Jakku - Rey and Finn flew through this one.
Annihilator - This one was stolen by Pirates and could possibly be a rebel SSD, since these pirates are described as being rather kind and almost benevolent.
Also in the latest book, Empire's End...
The Eclipse is talked about heavily. It was sent away from the empire to be the first ship to form the First Order. This book confirmed that the First Order had the Eclipse and it was barely used at the time, so very likely it will still be in service for the remaining two films.
I would seriously bet you we will see the Eclipse in Episode 8. I believe it was mentioned in Aftermath specifically for that reason.
And if the First Order has a SSD - there's a very real chance the resistance or remnants of the New Republic might eventually show up with something similar.
So we've seen alot of talk of SSDs lately in the books, and I'm certain Episode 8 will have at least one if not several. Corellian Conflict proved a nice alternate way to play, and could have been a test to see how well 500 point games will go.... All of these things make me think we're going to see Super Star Destroyers next year. Maybe announced in December or January of 2018 for a summer release?
