I thought Leica already admitted to it being CMOS, or at least said CMOs was the future....
Personally, I am watching the M10 for an indication of the viability of the entire digital M system for me. I was close to buying a M9, but decided to wait because I wanted better high ISO, where quite a bit of my work is shot. In the meantime, Leica pricing has called into question the viability of entire brand as far as I am concerned.
If the M10 is priced in line with the new 50 APO Summicron, then it will likely mean I never buy into digital M because I need to know that future bodies are not going to keep going up and up and up. I don't want to think this way, but the 50 APO summicron seems to be priced cynically and I have to wonder if it was to test the market tolerance in advance of setting M10 pricing. Sadly for me, it appears that many will gladly pay far in excess of what I can afford. When the M8 was produced it was about the same price as a top of the range pro SLR. In fact it was less. The M9-P is considerably more than a Nikon D4, 2.6x the price of the D800 and the M10 may well disappear into orbit.
Some people say Leica is only one great Fuji away from serious trouble, but I disagree because the brand is stronger than in a long time. Just look at people all hot and steamy over the 50 APO Cron. I do, however, believe that Leica is one great Fuji (and one absurdly priced M10) away from losing all but a fraction of its remaining working photographers, who buy into systems and look at far more than the price of a single unit at one point in time. This has no relevance to Leica balance sheets, but it is sad nonetheless. Leica's strategic partnership with Magnum - perhaps the most idiosyncratic of all agencies - would appear to be an effort to cling onto the link between the brand and world class photography, which is growing ever more tenuous with time.
