This is my guess in which planes will be updated. Everything in parenthesese are new planes that may come with each remodel.
- Spit & 109 (Thats a given)
- B17 & B26 (B17F, earlier B24)
- Tiffy, Temp, Hurr & Moss (with fixes to moss FM and DM, might add all fighter varient of moss)
- 110 & Ju88 (another ju88 model, solid nose version? and maybe me410)
- Lanc (Helifax)
- Ju87 (version with 37mm on wings, may add He-111 around now)
- P40 (add N version and maybe P39)
- Me 126, Me 262, Ta-152
- Boston, A20, C47 (B25 and A26)
Then move on to another Theatre.
If it is PTO then:
- F4U
- F4F, FM2, F6F (F6F-3?)
- A6M2, A6M5B (A6M3)
- TBM, SBD (Hell Diver)
- B5N, D3A (later version of B5N and Judy)
- Ki61 & N1K (Ki44)
- Ki67 (Betty)
- (Brewster Buffalo, beaufighter)
- (B29, no A-Bomb possibility)
Eastern Front
- Yak9u, Yak9T (Yak-3)
- La5, La7
- IL2 (IL-4)
- (PE-2, PE-8)
- (SB-2, Tu-2)
- (Ju52)
These are only planes, I'm sure some new gv's will be added with each theatre.
