A jet derivative of Aces High is possible and I think would create some excitement to the game.
I'm hoping we'll get the F-86, MiG-15, F9F Panther/Cougar, B-29 SuperFortress, Gloster Meteor, Lockheed F-94 Starfire, F-84 Thunderjet, Hawker Seafury, and LA-9 eventually to AH as a Korea War planeset. Since none of these carried missiles (they were armed with the M2 .50 cal or Hispano cannons), the weapons ballistics are already covered.
I think the first four to be done should be the F-86, MiG-15, B-29, and F9F, as they seemed to be the principle aircraft used in the conflict. Existing planes, such as the F4U-4, P-51D, IL-2, and both Yaks, would round out the potential planeset.
Of course we'd also have to update available armour to introduce the Pershing and Soviet T-34 tanks.
