If history has anything to say on this, Fuji is the most unreliable on any future predictions. They put out Acros at an outrageous price and cashing in on it. Not much change in management is needed to pull that plug though. In fact they've pulled films from market on very short notice, they've re-introduced some on similar short notice. I would not count on any film product Fuji makes long term, sadly.
The only players that, at least for now, are future proof in film production are Ilford and Adox (all other brands I'll leave to that audience). Kodak is likely to continue, so long as Tarantino and few others keep ordering film. Once Hollywood drops out of film use, anything can happen to any Kodak film.
What can save it all, and also improve supply and choice, is demand. I'm not sold current trend is future proof though. There is a major generational change coming in a decade. Those in their 40's need to start taking film seriously and show to those in their 30's, so those can shoot the word down to those in their 20's.
Look at the generation Z? I have no numbers, but I see nothing in film interest that would be sustaining demand needed to make film. Seems like drop in the ocean. Phones have so much to offer these days in photography, even digital cameras may have their coffins in sight, at least the consumer level ones.
