If their fighter scale game is anything to go by I'd say we're getting the entire Imperial/Rebel fleet and the proverbial kitchen sink. Will be interesting to see how they deal with the elephant in the room; the Deathstar.
Concerning the game, come on! If it's good we'll play it, if not we'll have another source of models for our other games. What can possibly go wrong? Except for it being horribly expensive of course, but we're all grizzled veterans to such hardships, no?
