Wrong.
There is an M9, M9-P and now M9-M.
It's just called M Monochrome for PR purposes. This camera is an Leica M9 with bayer layer removed (or whatever it's called) and a few software tricks. (And added price tag, novelty!) therefore, "monochrome M9" or whatever people want to call it. It's not a different, specially built from the ground up, new camera, it's a new version of an M9.
I think you are the person who should stop spreading miss-information.
Thank you.
