For a lot of reasons, I think the "revival" of the 9mm and/or .40 cal will be less than some might expect. The wondernine is to some extent an open-carry or duty gun, and the onset of Shall-issue would have diminished its popularity all on its own. Sure, plenty of us will want a high-cap 9 or 40 in the nightstand, but some will use their concealed carry gun as a home-defense gun. Some people can't afford two of them (pray for us), aren't gun-nuts enough to buy two of them (really pray for those people) and some just prefer to be as proficient as possible with the same gun.
High-cap guns are no longer the latest, greatest technology, and folks are no longer so crazed with having the latest thing as they once were. As an example, when I was a teenager who had never shot a gun before, I thought the Sig 9mm was the hottest thing going. That was in the early 90's. When I bought my first handgun in my early 20's it was a wonder1911 (a Para-Ord. 13.45). Now, I own a S & W Mod. 19 revolver and am hoping to buy a Para LTC, (single action, single stack). Yeah, I know, I ought to get a .22 for practice.
The AWB caused a certain reconsideration of the 1911 and the revolver. Those who "converted" may never return to the wondernine camp, especially with all the high-cap .45's out there, including 1911's and the new .45 GAP's. A lot of our preference for guns is emotional, is shaped in our early years, and won't be changed by practical considerations.
