True - there's a lot of unknowns at the moment. So many, we likely don't even know that we don't know we don't know them.
Has anyone announced, beyond FFG, that they have a license for the new films stuff? What scale of game are they going for? A skirmish game for Star Wars could work, except FFG already have Imperial Assault, which has slightly ropey (well, in my opinion) models - ropey enough to put me off the game.
What if, against expectation and what we've seen so far, the films turn out to be terribad? Yes it seems incredibly unlikely given what Disney have done with Marvel, but there's always that chance, especially with something as beloved as Star Wars (though I'm sure there's many a neckbeard getting into a horrible sweaty lather about just which crude comparatives they can use to describe just how much Disney just betrayed their childhood).
