I really like the way AH has modelled a/c flown by nations other than the big 5. The Italian planes, the Finnish 109, and the Brazilian P-47 come to mind.
It'd be nice to see this continue, with perhaps a Free French P-63C KingCobra, or a RAAF or RNZAF Spit MkVIII or Bristol Beaufighter or Mossie.
And I believe the SAAF operated P-40s? A nice late model P-40 in SAAF desert livery would really be nice for the North Africa scenarios.
