Given that its markedly superior in just about every way to the B-26, B-25, Ju-88, BostonIII, He-111, Ki-67, and G4M, I would not be at all surprised if useage plummeted for them. The B-24 only has 2k more ordnance (although admittedly spread out better), though it is likely to be less survivable, given that the Tu-2's speed will likely leave many fighters struggling up the 6.
I foresee a significant drop in A-20 usage as well, given that it looks to be more effective in the GV bombing realm, given the two 1000kg bombs the damn thing can strap on. Not to mention the 9 100kg bombs, if you're a good aim. And the 4 250kg bombs.
