So will we see any expansions launch On or Around the time of the base game? I'm guessing we'll get 4 options, though they may not come in "4" boxes.
Additional Squadrons-
I could see extra squadron packs being sold with 2-3 squadrons inside each, or perhaps less, but it all depends on the price point.
Imperial Ships - Depending on whatever they announce for X-Wing at Gencon, we could expect some smaller Imperial Ships, IE Lancer, Gozanti, etc.
Rebel Ships - Wave one seems too soon for a Mon Calamari, but unless they release a GR-75 transport... what else IS there?
