I hate to say it, but I think the instant-film-as-we-knew-it era is about to be over. In Polaroid's heyday, instant films (both pack and integral) were produced in such huge quantities that Polaroid (and Fuji) could afford continuous and extensive quality control. Fuji still does with its Instax films, which look great and are very reliable from shot to shot.
While small players like Impossible and New55 may be able to assemble instant film, it will always be manufactured in very small quantities. Fuji's discontinuing FP-3000b proves that there is just not a market for a volume producer of instant pack film. And, as we've seen with Impossible's integral film, small quantities mean high cost and poor quality. These will always be novelty products.
I shot some outdated 8x10 Polaroid recently and was amazed at the quality of the material, with crisp, beautiful tones across the image, consistent from shot to shot. While I admire Impossible for re-introducing 8x10 instant film, they will never reach that level of quality.
However much I love instant peel-apart films, I believe the world where they could thrive and be refined is gone forever.
