I have a sneaking suspicion that Star Wars Rebels might just take us all the way to the final battle of Rogue One - and allow us to see events from that film through the eyes of the ghost's crew. I don't know if that will be the series finale or not, but I can totally see them doing that and filling in background details from that story with events going on for Hera and the Ghost.
Do you think they'll take it that far?
