How many late war medium bombers do we have in game again?
I just posted HTC's staff's take on the matter. I'm not going argue about it with you.

I totally agree with pyro that it is one helluva plane. One of the best airshow performances I've ever seen was flown by one. It was quite a sight and sound to see a plane of that size being thrown about....high speed passes that were pulled into complete loops, beautiful. Still, I personally hope that is pretty low on the list of priorities for HTC.
1) Our US planeset is already huge compared to the other nations.
2) As a bomber it would draw lot of art recources and would take a longer time to develop than single engined fighters for example and still be somewhat redundant as AH already has the A-20.
3) It's involvement in the WWII itself was rather short and small compared to many capable planes left to be added.
