To my knowledge, derringers aside, there are only four pistols currently in production that are chambered in .32 Auto:
• the Seecamp LWS 32, introduced in 1985;
• the Beretta 3032 Tomcat, introduced in 1996;
• the Kel-Tec P-32, introduced in 1999; and,
• the North American Arms Guardian 32, introduced in 1999.
These are all true microcompact, pocket pistols having a bulk volume (B ≈ L×H×W÷2) of no more than 10 in^3. I point this out because today's marketing propaganda claims that higher capacity subcompacts chambered in 9 Luger are somehow microcompacts, despite being slightly larger subcompacts (B ranging from 10 to 20 in^3) than their single stack predecessors.
I regard all four of these pistols to be modern designs. After all, the 5th generation Glock 17 introduced in 2017 is regarded as modern, yet it is virtually identical, except for a few ergonomics tweaks, as the 1st generation version introduced in 1985.
Again, all four of the above, extant .32 Auto pocket pistols are small, as seen by their respective unloaded weights and bulk volumes:
• Seecamp LWS 32 — 11.5 oz, 6.3 in^3;
• Beretta 3032 Tomcat — 14.5 oz, 10.0 in^3;
• Kel-Tec P-32 — 6.6 oz, 6.7 in^3; and,
• North American Arms Guardian 32 — 13.5 oz, 6.0 in^3.
Given the Tomcat is the heaviest and bulkiest, one can assume it has the lowest recoil. Genitron.com reports calculated free recoil energy for each pistol firing the same 71-gr FMJ round as follows:
• Seecamp LWS 32 — 1.81 ft•lb;
• Beretta 3032 Tomcat — 1.55 ft•lb;
• Kel-Tec P-32 — 3.61 ft•lb; and,
• North American Arms Guardian 32 — 1.59 ft•lb.
In addition to the Tomcat having the lowest free recoil energy, it has, by far, the most available real estate for hands to find a grip that will tame its recoil. However, none of the above four .32 Autos has a recoil energy close to the 5.35 ft•lb generated by the 9.4-oz, 7.6-in^3 Ruger LCP that many find to be unpleasant.
I doubt we'll see anything new being chambered in .32 Auto anytime soon. As I recall, when Beretta introduced the Pico they announced they'd be selling a .32 Auto conversion kit, which never materialized. I remember seeing someone selling .32 Auto conversions for the LCP, but those dried up quickly.
For innovation in the nominal .30 caliber realm, .30 Super Carry is where the action will be, and it may not be much action. In terms of pocket pistols, I doubt anything will be designed in .30 SC, as the round has too much pressure and would generate too much recoil.
