I'd like to see the ships and pilots from Star Wars Rebels make a future appearance in X-Wing.
I would LOVE a Zeb tie fighter card
I'd quite like to see them revist some of the classic pilots at different ponits in their careers. Rookie Wedge or Rogue Leader Luke or whatever (sorry if my mythos is all wrong, but you get the idea).
Even some pilots that are very much in the fantasy bracket - what if Chewie ended up having to fly an X-Wing? or C3PO?
Would make for some interesting scenario or campaign packs!
I wonder if they would make mini expansion packs that would just have character cards in them. In theory they should be able to make those in house like the print on demand scenarios for Lord of the Rings.
