I haven't seen the prices go up at B&H yet, I just bought another load of Portra 400.
I actually don't want to buy so much that wouldn't be able to shoot it should they discontinue their color negative films and C41 processing becomes harder to find/much more expensive. A year makes sense, a five years' supply doesn't.
This is kind of like the discussion of $10 per gallon gasoline (avoiding politics, lol) - at what point do you quit driving? I see used 2007-era medium format digital systems in the $6000 range now, and those would be good at lower ISOs, just like film. So frankly in 2-4 years I bet a lot of us will be converting, especially for color work. If you can get a 39mp Hasselblad HD3 for $5K then that's a sweet spot for many.
I don't doubt that B&W film will be available indefinitely and home processing isn't hard so my cameras won't be obsolete. It's just nice to have color options.
I quit driving when it's impossible, not when it's expensive. Pretty much anything else, including photography, would be sacrificed first. There is no other way to get from my house to my job, for example.
I didn't even cut down when gas went from a buck a gallon to four bucks a gallon, I just spent less on other stuff.

Most blest is he who lives free and bold
and nurses never a grief,
for the fearful man is dismayed by aught,
and the mean one mourns over giving.

A lot of telecommuting will happen as gas prices increase....
Regarding film prices, it is just like the weather. Everyone complains about it but nobody does anything about it
