Should I look for full frame digital M today the M262 is the answer : CMOS is more reliable than CCD inside M9, more silent shutter as it claims ( hope it also means lesser vibration at lower speed as I find the lowest I can do with M9 is 1/30 second ), larger battery with more juice in it, larger and higher resolution of LCD in the back .... live-view is one of the benefit of CMOS moreover for street photography I sometimes do off-finder
Should Leica can make M262 more reliable white balance for indoor as well more predictable exposure than M9, then I would be happy and start saving money for it
