Personally my money is on a Dust: Tactics like squad based miniatures game set in the original trilogy timeline. It may even be called Star Wars: Tactics.
This would mean highly detailed quality prepainted plastic sculpts, with varied molds for each model. The base set may consist of Storm Troopers and Rebel Troops. We may even get some small AT-ST's and/or power armored Storm Troopers. First round of expansions will probably be secondary characters, and "hero" sculpts of important/famous characters (Luke, Han, Chewie, etc.). Like Dust, they may even include a terrain "board", though I'm unsure just how strict the license is regarding the fact that they can't make "board games". The current license holders, Hasbro, tend to interpret this as "make the worst board games you can and slap the Star Wars logo on it". The Dust Tactics style approach would allow them to get around this in a way while still producing a board game like experience.
This would scratch everyone's "want more Star Wars stuff" itch, plus they'd be tapping into both the wargamer and rpg markets since some would purchase the game just to use the minis in their pen and paper campaigns.
What do y'all think?
