My source tells me there will be hangars, runways, carrier groups, factories, and cities in the next version.
Oh, also a check 6 feature, a flight recorder option, custom gunsight ability, squad logo art, and perk planes based on a value perk point basis.
Ahh, almost forgot. Vehicles including the m16, ostwind, panzer IV, lvts, and m3. Rumors are there will be a german jet bomber, too.
