It's not crystal-ball gazing, but a realistic development down the line. This is what I am worried about. But until such a thing actually happens, go and buy the stuff, and shoot it, process it and admire it. Back when Velvia 50 was "brought back", there were many, many, many more analogue photographers there in the market to support it. The problem is the market is not so analogue now, but oh-so-digital (eeeeeeek!).
We've got petitions on the go here in Australia too, but FujiFilm Australia has said nothing about discontinuation of the particular films.
