Really wouldn't surprise me if it was something to do with Aphra and 0-0-0 . The driods are already in Imperial Assault, she has a ship, large base? Likely Scum, because they need more large base ships and the crew could potentially be both Imperial and Scum crew cards meaning Imperials could get some decent 1 point auto actions from it.
The comic is picking up traction so it's a logical choice in my opinion.
Beyond that, I'm guessing the First Order Epic Ship.




It is a new Scum large ship – the Meson Martinet freighter from Force Awakens with Sidon Ithano (the Crimson Cosair) och Quiggold!
