Why not release an early war set of, say, ten planes, i.e. I-15, I-16, I-153, Gloster Gladiator, Ki-27, Claude, PZL11C, etc. and have an early war MA? Once the early war plane set gets built up so that it can be "mated" to the regular MA, just squish everything together. Oh yeah - if there is an early war MA, they should also stick in some early war bombers and CAS planes like the Blenheim, Do 17, Battle Bomber, Hs 123, etc.
