Perhaps these are going to be on-screen in Episode 9 and they had to wait to present them until now? 

This is the rumor, it's starting to feel more credible. If they appear in Ep 9 then we may be able to assume other sequel ships can appear in Armada as well; making a rebel huge ship the MC-85 and not the viscount.

Wasn't something written somewhere that a few ISDs were still in service during the "sequel era"?
