For personal work, this pretty much does it for me.

+1 ... All my work is personal now.

In addition to the M-D (my favorite M and quite possibly my favorite camera of all), I also need a TTL camera for macro, long lens, and precision tabletop work. I don't need a lot of fancy features: an accurate exposure metering system, an excellent viewfinder, responsiveness, good dynamic range and low noise at reasonable ISO settings. Good control ergonomics are essential. 24 Mpixel is a good resolution, depending on format. Format ... well, that depends on what I want a specific camera for. For close up, long tele, and macro work, APS-C and FourThirds format work nicely. For ultrawide and portraiture, FF and larger work better, giving more options in focus zone control.
A huge consideration for a camera purchase is the range of lenses available for any specific camera ... both quality and cost. I already have a full complement of Leica R lenses that I'm very happy with, same for Leica M lenses, so it makes sense to stick with Leica bodies that are well optimized to use them. My requirements led me to buy a Leica CL, replacing my Leica SL (which proved more camera than I needed/wanted), and I'm delighted with it: It proves a perfect complement to my M-D.
Of course, I have other cameras (Light L16, various Polaroid SX-70 and derivatives, Hasselblad SWC, etc) which suit either fun or specific niche uses better than the two Leicas. And I have a couple of film Leicas (M4-2 and Leicaflex SL) so that I have options for film photography as well as digital capture using my Leica lens kit.
The key, for me, is that once the cameras have passed a certain point of fundamental usability—a combination of resolution, dynamic range, sensitivity, control ergonomics, viewfinder/focusing system quality, and lens availability—I'm much more interested in using them than adding to them. What I really want is a camera that disappears when I use it, that lets me just concentrate on seeing what I want to photograph than distracts me by making me concentrate on managing it.
I have to admit, I don't look for new cameras—film
or digital—anymore. What I have is more than enough. New cameras will come along now and then, I'm sure, but whether I buy one or not is purely up to the whim of the moment. I'm much more interested in using the cameras I have now and making photographs...
