I think we need at least 4 VVS bombers total... 2 of them optional but would be nice. 2 early war (IL4 and SB2) for scenarios. Of these the IL4 was probably the less common of the two, so it would be optional. And 2 mid/late war (Pe-2 and Tu-2) for general use (and scenario use). The Pe-2 is a must, whenever they get around to it. The later war 1944 Tu4 performed better (was faster and better weaponry/bombload) but is optional.
My thoughts on VVS bombers. General bombers I'd like to see: He111 (rather light load, though), Ju188/388, Halifax, Sterling, Blenheim, Mitsubishi B2M (precursor to the Betty, but it was pre-war, so we'll never see it), Handley Page Heyford (pre war, well never see it, but I've GOT to build a model of this thing someday before I die!), the G3M betty, and of course...
The number 1 bomber I'd like to see in AH but NEVER will, is:
The Junkers Ju86! (it's a sweet fusion of ugly and elegant)*
*= or maybe I'm just sick
