Im very very sure that HTC will add Bf-109G-14. The G-14 is basically a 109G-6 with MW-50 for extra power.
expected lineup for 109s
109E-4, F-4, G-2, G-6, G-14, G-10
Spitfire? I'm sure Spitfire LF Mk. IX to clear that gap between the early spit 9 and spit 14.
expected Spit lineup
Spitfire Mk. 1a, Mk. Vb, Mk. IX, LF Mk. IX (clipped wing), LF Mk. VIII (clipped wing), Mk. XIV, LF Mk. XVI (clipped), Seafire II, Seafire III (The most common)
