I'm seriously considering getting another M9 while I can get a new one, even if the sensor will be corroded by gamma rays from outer space before I need to use it. I've long been hoping for a lower tech digital M, which it looks like won;t be coming. FF sensor, no motor, no LCD, a few dials to set ISO and exposure compensation if it needs to have AUTO shutter. Let the camera read my 6-bit lenses and be able to deal with a non-coded lens. Frameline selector please. CMOS, CCD I don't much care. The M9 sensor does most everything I need besides a low enough ISO. Hardly ever shoot over 800 or 1000- never do with film either. I like my ISO 20 Rollei Ortho and my ISO 40 PanF+ just fine. I'd been longing for an MP-D, but would happily settle for an M7-D. I'd buy two of them.
But, cameras are a product, and products rarely manage to stay the same any more. Leica is pretty unique in having kept so much the same for so long. Look at the F and the F5, and now the D4 or 5 or whatever they're up to now. The M still has an optical VF - something I don't see lasting terribly long now that the EVF is there. More clamoring for more info in the VF, look at a D4 - how that became 'normal' I can't imagine. Even the F4 was busy, tho not cluttered. I've not shot a real video camera in decades, I can only imagine how difficult it is to see through the info displayed in one of those now.
I'm not terribly concerned about being passed by the fast car. I have tools that do exactly what I need, more than I need in some cases. I can make prints as big as I want without much trouble. Assuming the digital bodies last I'll be using them as long as I can, till the DNG file format is overtaken by some faster better file and the computers can't read a DNG. I used to say I'd start coating glass plates if film went away, now I kinda doubt it. When push comes to shove I'll move to the M of the moment if I still need a digital RF.
I still shoot lots of film, heck I teach film, and am already far behind the curve of understanding how all these digital camera features are helpful. They change so fast keeping up is almost a full time job. Focus peaking? I've seen it, tried it out with a 35/2 v4 on a Ricoh something or other with the M mount. Seems kinda silly. ISO 264,000? really? No thanks. I'm old enough to remember when it was dark at night, and that meant you couldn't see things. That was part of life. But then we rode bikes without helmets and knee/elbow pads and cups, had cars without seat belts, ate food without genetics. And still thought we had it all.
