Well, for the first time ever I just now placed an order to assure myself a modest future supply of an announced discontinued film product.* Ordered 25 rolls of 120 Provia 400. Added to the 5 in-date frozen rolls I currently have, that's 30 total.
Combined (at least for now) with the still available 120 Provia 100 for most situations, and at my modest level of color use, 30 rolls of 400-speed is probably a ten year supply for me. And chances are good that the E-6 chemistry will also be discontinued before then anyway. At least at that time I can presumably also order up enough home processing kit to finish off my remaining rolls, if they haven't all been cosmic-rayed to death beforehand.
Unless someone like Harman eventually steps in, or a Harman partnership together with someone else, as Matt speculated in an earlier post, I'm pretty convinced that color film photography of all types will die off completely within my lifetime.
It's the unavoidable Tyranny of the Bell Curve. Most available consumer money clusters around the mean of the normal distribution, so most of the targeted consumer products do likewise. Step too far away from that mean, as we here all have done, and your product choices dwindle very, very quickly. It's the price to be paid for not running with the herd.
Heck, not too long ago I read an advertisement (by Sony, if I remember correctly) that was literally begging the photographic consumer to consider using "real cameras" with which to make their photos. The "real cameras" were Sony digital point-and-shoots, as opposed to the not-mentioned-but-inferred smartphones.
So already the technology that triggered the film crisis has itself begun to drift dangerously away from that same mean.
* Kodachrome doesn't count since the unique processing also died with it, so there was no point in securing future supplies.
