I respectfully disagree, i.e., I don't think the M system as we know it was inevitable. Yes, there were the Leica IV &, later, the Casca II, but they were not conceived of in a vacuum. IIRC, the Leica IV & Contax II prototypes were contemporaneous (1934-5?), but as of 1936, the Contax II existed as a working camera that was relatively successful w/advanced amateurs & professionals. What other competing system 35mm RF was there in the late '30-40s? Certainly not the Kodak Ektra. I'm not saying that Leitz simply copied or updated the Contax (as Nikon effectively did), only that it was a competitive kick in the pants.
As far as the IIIg, I brought that up because it demonstrates that even in the company's early days, there was a strong conservative faction within Leitz that simply wanted to improve the basic Barnack design rather than go w/the more innovative M. My point is that but for Contax II, or maybe the Casca II (assuming it had become a success), Leitz may have taken longer to greenlight Leica IV/M production or they might have gone w/something more like the bottom-loading Canon RFs (which actually adhere more closely to the Leica IV form).
Well, we're dealing with counterfactual conditionals here, and matters of opinion, so neither of us can be proven right. All we are disagreeing about is the extent to which the Contax influenced Leitz. I do not doubt for an instant that it did; but equally, I do not think that it was as important as you say. System RFs? Well, the 1934 Robot didn't have a rangefinder, but it eventually grew one, and the Retina IIa (1936) didn't have interchangeable lenses, but it (sort of) grew them later. Were Perfexes (nominally) interchangeable-lens? I forget. Alpas had interchangeable lenses, rangefinders and reflex viewing in about 1942.
Bear in mind that in the early days, no-one was sure that 35mm was going to survive, so quite slow development was no great surprise.
Cheers,
