one of the near or nearly near patches, post post release polishing, were dedicated not to new planes nor new strat, but just new weapons for what we already have.
R4Ms, 40 to 22,000lbs bombs for the RAF, Schrage Musik, Panzerblitz rockets, skip bombing modeling, 20mm quads for the Ostwind-Whirblewind conversion, NS-23, NS-45, VYa, Mk103?, BK3.7/5/7.5, 6xMG81 pods (Ju87D-4), twin 151/20 wingpods, 20mm M2 for the USAAF fighters that could fit them, etc.
Some would have to be perked (the same way perked planes are), some of them would require a full separate frame, but it'd be neat, as many planes are rather empty in comparison to what they'd've looked like in the hangar, IRL.
