Denholm, I believe Skuzzy made the quote you're thinking of, and he said it in the same breath as the word "B29" I think, so I wouldn't hold my breath. [EDIT: actually, I think he said it in the same breath as the words "tall boy" -- I still wouldn't hold my breath]
I think it was more of a hypothetical thing, where they *could*, theoretically, do that.
I don't think we'll see it for some time. Heck it's taken them 2 years to upgrade a fraction of the planeset to new standards. I'm guessing it will be 4-5 more years before every last SBD, D3A, and P40 are upgraded to full quality. That's not to mention future CT scenarios, and other things they've got on their plate. I don't think AH will ever go outside of WW2, but this is just my personal opinion.
