Planes, of course.
How many old models left, and how long to get the number of new models we have? I'm going to go with graphics, as I'll be dead before all the planes are finished.
But what is the criteria for new planes?
Which ones first?
I was looking into the B-239 last night. There were less than 100 in the FAF. The Finns did amazingly well with them, and it is a fun plane to fly. But there are many planes that were produced in larger numbers that have yet to appear.
And, how finely should the sub types be modeled?
This is a coding issue, I believe. At what point do subtle differences between types become indistinguishable in the game?
Personally, I would like to see more early war birds. How about a French Dewoitine 520? Or maybe a Fokker DXXI? To oppose an AVG P-40B, a Ki-43? Probably destined to be LW hangar queens, for sure, but easily as numerous as the B-239. And good for early war scenarios.
