With the A20 performing as well as it does as a fighter/bomber I think the need for an A20 type fighter/bomber is pretty well taken care of, don't you

Lots of stuff has a higher priority than the A26. For me an SB2C would be nice, P400, P63, He111, GM4, Ki43, Ki45, Ki100.......M10, Panther, JS1, KV1........thats just pre top of the head stuff.
I would love to have the B29 in game. Although just thinking about the low level LANC suicide squads does tend to turns me off to the whole idea of more Allied heavy bombers.
