BoM is actually not even OFFICIALY anounced
and the "new" aircraft so far shown in WIP screens were:
I-16 Type 28 (at least a version with canons)
Ju88A-4
IL-2 singleseater
IF 1C is realy focussing on winter 1941/42, i hope they will also bring a P-40B/C. Used in action at that time in the Moskau area.
