Here's why Korea would be done first (assuming they go forward). Three of the more common fighters are already modeled (P-51D, F4U-4 and Yak-9U). Plus, the B-29 was big player and modeling that will cross back over to the late-war MA. New planes added would probably be the following;
F-80C Shooting Star
F-84 (3 versions) Thunderjet
F-86 (3 versions) Sabre
MiG-15 (two versions)
A-26 (two versions) Invader
AD (three versions) Skyraider
F9F (two versions) Panther
Meteor (probably two versions)
Sea Fury
La-9
La-11
IL-10
F-94A Starfire
F2H-2B Banshee
F2H-3 Banshee
F7F-3N Tigercat
F3D-2 Skyknight
B-29A Superfort
