If they can offer a b&w only version for, say, $1000 more, I expect they will sell enough for it to be profitable. People buy the M9-P for $1000 more...
I was thinking a chrome M9P before this thread started. I'd have to sell a lot of gear, but that would be a good thing. Thought I was a die-hard B&W film guy, but now I look upon digital as a different/seperate medium as an opportunity for growth and a personal challenge.
Having better high ISO performance would be a game changer for me and it wouldn't have to be that high, perhaps 1250 or 1600.
