I never liked the G43 when there were better options (in my opinion) like the Shield. The G43 grip is too small, and I don't have large hands. The trigger was heavy compared to other Glocks, which I didn't necessarily think was a bad idea for something that a lot were going to drop in a pocket. The grip was too short and my finger slipped off with a flush fit magazine. That said, I thought it was a very trim piece and as small as Glock could make a 9mm. It's slim enough that adding a little more girth and length for a 10rd mag will probably make it fit my hand better. The G48 with the longer barrel and grip than a G43 won't be as concealable, but not by much. Certainly not a pocket pistol. More concealable than a G19. There are lights and lasers that clamp around the trigger guard so they'll work for the G48 as well without compromising its concealability. I don't think there will be a G17 length version. That niche is a small one and 10rds seems like a magic number since leftist politicians don't have to remove their shoes to count that high. Since that can be done in the G48 envelope, I don't think they'll go bigger. At some point, an aftermarket supplier will offer a longer slide and barrel, and magazine extensions. That will get you up to G17 length. I haven't done the math, but a G43 slide with a compensator will probably bring it out to G17 length. Add a small RDS and you can turn your G43x into a mini-Roland.
