The main reason a lot of places got confused is that Fuji switched Acros 120 from single rolls to Pro-Packs. So if the person doing ordering is not on top of things, the deleted/no longer available catalog number will lead to the wrong idea that the film has been discontinued. Just my thinking on the subject.
As for the long term, Acros seems to be doing fine. I have been ordering quite a bit lately and each time I am getting stock with really good dating. When a film continually has the same exp date it can be a first clue.
