This discussion is very interesting. Not the least because partisipation by experts like Tom Abrahamsson.
First of all; if there is going to be a M9, M8 must first become a promising success. With only 6000 examples out there, it is far from a success. Must be.
So, if you want to see a M9, buy a M8!
To make the M-system a success a cheaper camera that appeals to younger buyers must be introduced on market. - Otherwise the M-system will die out with us 'the old guys'. (The RFF rangefinder.com playes a very important role in introducing the Leica cultrure to new users, old and young!)
This cheap version shall not be the M9 (that can come later), but a digital CLM (something looking like this;
http://www.cameraquest.com/leicacl.htm )- a cheaper, compact M-camera with, say, 8 million pixels and a 1,5 crop sensor. - Can Epson/Cosina do such a camera, then Leica can do it even better (..and cheaper...?). Now that Epson has stoped producing the RD-1 then this segment (M-compatible 1,5 crop camera) free to anyone who want to exploit it. Leica should rush to fill this gap.
- What Leica is not good at, is rushing, though. but that is a thing they have to learn to stay afloat in the digital world.
The M9 should be the 'perfect' next high end camera that exploits any significant development in resolution, low noice/hight ISO, crop factor - whatever it might be.
Before all that, the M8 success must be assured. Leica should go thru all the bad issues that has hit the M8 and try to improve them all to close to perfection as it goes and launche a 's'-version, with the UV/IR filters in the box. Say, by Chrsitmas. Hopefully, by this, squeezing another 10.000 units out of the market.
To the Leica organisation in Solms I say; good luck!
