I think that build quality and engineering is a must for even the lowest end of pro film cameras designed for professional shoots. There's no way they could skimp on anything, really. Camera jams too much? Image not steady? Camera unreliable? Then a production company is out $1,000's - possibly 100's of thousands. Nobody would use that camera, and out of business that company would go... and a trail of lawsuits behind. Even the low-end Revere 16 I owned - similar to a Bolex I guess (though the Bolex is a much nicer camera), was absolutely solid, beautifully constructed, and very reliable. And yes, black and white will most likely survive as a niche/pro/special purpose item, possibly. But as you state - R&D will cease and prices for whatever film is available will skyrocket. Given that there is a cheaper substitute even for this... a well-done digital black and white is no slouch, especially in 35mm... in the worse case, what remains prices itself out of the market. Larger formats is another matter entirely... and perhaps I should have qualified, and I hate to be the alarmist, but this news more so than a lot of the other stuff going on to me points to a definative "for all intents and purposes" endpoint for small format color - and possibly even black and white, film production. I hope I'm wrong.
