For a possible third wave as far as I know the only Fighter Types left are the B-Wing and the TIE Bomber. And as a token maybe the Shuttle Tydirium.
As far as the rules show Jay Little made different Unit Types, and sometimes both factions get one of those. For Example the TIE Interceptor and the A-Wing comes both with the Boost special rule. And the Millenium Falcon and Slave I are big ships with multiple Fire Arcs and some other specials. My point is that there are new rules build in and then the Empire and the Rebel Scum get their own versions.
So for the B-Wing and TIE Bomber I'm expecting some kind of build in Missiles. Power 3 or 4 Weapons which need a Target Lock and don't modify Range defense. If they don't use a Lock they have minimal Blaster Fire as a secondary Option. Less at the TIE Bomber, more at the B-Wing. Thats what I think about it, any other ideas?
