I agree on the star wars rebels comments. That would mesh very well, as it is set at right about the same time.
Also, my sons would love that.
Episode VII would be nice, and I'm sure will happen, but we need some episode VI first.
That would be the most likely, we already see in Star Wars X Wings, that Fantasy Flight have done artwork for the Lorthal Rebels.
An expansion where people could experience a story on the planet and have the ezra and the bunch be allies would probably be awesome. Especially since if people dont like the rebels then they can miss an expansion and they wont feel pressured to get it.
Would be awesome if FFG would do this so there can be Dad as the Imperial Player, with Mom, Daughter and Son would be the Rebels and could experience a Star Wars story together as a family.
I don't see Episode 7 coming to soon, maybe a big Box expansion at the end of 2016.
