My guess for order of planes for ETO ToD:
B17G, B17F added
B26B, B24D added
Tiffy, Temp
Mossie (with fixed to FM and a new version added))
Lancaster, Helifax or Wellington added
Hurricanes
ju88, He-111 added
Ju87, another Ju87 version added
110, Me410 added
152, 262, 163
Though some planes like P40 were used in the ETO, it would more likely be updated when PTO rolls around.
