Doubt it as I don't see a relation. Adding the BK37 now doesn't save any work over adding it later.
I am glad to see three new guns, MK103, BK37 and BK5, in the next version.
Out of curiosity, is there anything else that used the BK5? (Not the test on the Me262).
Why stop there?


410 Km/h max, 16 shells and only 23 built! Perk!



The German Sturmovik!

Jokes aside, the Hs-129 did have a Mk103 option (100 shells), as well as a Bk 3,7 one (12 shells)...
...just like the Bf-110... with
60 shells for the latter...
