Not everyone who owns an M8 is rich and drives a Porsche. And an M8 is not a DSLR, anymore than a bicycle is a Land Rover.
I have a bunch of M and LTM-mount lenses. I prefer rangefinders to SLRs--I just "see" and focus better that way. So I swallowed hard and bought an M8. It was cheaper than rebuilding my entire system with something I'd like less.
The used market in Leica and CV lenses and accessories is my salvation. Leica may have gotten me as an M8 customer, but not as a repeat customer. Apart from the M8 and one Leica lens I bought new, everything else Leica-related I own is used, a third-party brand, or both.
My reaction to the new Noctilux, 21/1.4 and 24/1.4 lens prices is: Are they crazy? Time will tell whether they will sell enough of them to make it worth it. Leica is going, it seems, for an increasingly smaller market that is willing to pay an increasingly steeper price. They've always done OK doing that before. But at some point, people will say, "there's a limit."
The M8.2 probably is not over that limit. The new lenses may be. The upgrade prices are outrageous. I'm probably not interested, so it's no skin off my nose.
I don't regret buying the M8. For my purposes, it's the best digital camera I have ever tried. I'd have been happier if it cost less, but I am very happy with the camera.
