Joe did ya see the high ISO from the B&W only new chip thats in the monochrome? Pretty clean at 10,000 ISO.
Rumors about an M 10 in the fall with new CMOS chip. Real clean high ISO. I would only look to Leica for rangefinder. Its where their really good glass is.
iso 10,000 M10 will make me pull the trigger for sure, I wonder how long the waiting period would be.
