Yeah, the salesperson said she thought they had discontinued it because they couldn't get any for awhile. I normally buy the 16oz bottle and had to purchase a 32oz. Luckily it keeps a long time in the fridge. As for the longevity of film, I think it is totally contingent on the studios in Hollywood to keep it going. With Panasonic and ARRI going digital it remains to be seen whether that holds true.

Correction: unless you plan on making an early exit, I think film will disappear in your lifetime.

From experience I would say that film is pretty much dead in the water in high end productions.
I hope it stays alive for photography but for video I think digital has surpassed it on enough levels to make it a better option.
I'd guess that of the remaining manufacturers, Ilford is most likely to stick it out to the bitter end. At least for B&W, the chemicals are not really a problem--kits like the ones sold by Photographers' Formulary can be produced and sold on a fairly small scale as long as the raw chemicals are available. Even paper can be made fairly small scale. Film itself is a problem. Making a good-quality film product requires pretty sophisticated industrial equipment and a high degree of quality control (the difference between Ilford and the stuff from eastern europe is noticeable). But there's always the freezer.
Since ilford seems to be opening new factories and introducing new products I think it's safe to say that they are getting to the point where they are becoming the market leader in B&W. I think that if they stick to that there will be enough demand in the future to keep the business sustained as there will always be a niche contingent keen to experiment how the original photographs were made before digital.
