One caveat from my old Econ professor;
"Marketing is bullshit" He started each semester with that being his opening statement (usually after asking unsuspecting advertising/marketing majors to raise their hands).
Without demand for a product it's all fluff. I do suspect there will still be demand, but what do I know?
Plenty of demand for MP film. Even when just little old me shoots a total POS, I'll still go through over 100,000 feet of the stuff.
