Since i started playing this game maybe a year or two ago ive been dyeing to see new German bombers...or any new axis bombers for that matter, its just that Germany had some decent bombers from the DO17-217 JU88-188 MAYBE HE177. You have both early war models and middle-late war models
so many different variants of German fighters to chose from maybe the three cannon 190 d12. Their is just so much variation that you could include with these German planes from installing new engines in the later war 109s (high alt versions AS i think)to all the different armaments including the 4 small bombs for the wings, different weapon systems.BF 410
Knowing what the answer would be, as it's said every time someone asks for another Spitfire variant. How many 109s and 190s do you need?

In terms of German bombers, I'd imagine the question comes down to how much use they'd get beyond historical scenarios. None of the bombers described have even remotely the survivability of the heavies or medium bombers in game already.
A lot of folks ask for the He111. Again, for the B of B scenarios it would be nice. I'd bet the house however that once the novelty wore off, it wouldn't get used even remotely in the MA. One HO shot by a 4 cannon bird into that all glass cockpit, and that's all she wrote. There is a reason they went to night bombing.
At this point I'd imagine the only LW bird that might get a fair amount of use if added might be the Me 410.
In terms of Japanese birds, the uses again would be scenario oriented. Ki-43 and Betty being the most obvious for that use. MA use would be minimal again as outside of the diehards willing to fight in less then the best, their use would be minimal
