What do they mean by "double digit" ?

I can sort-off understand it, but it seems that Fuji (especially) is looking to pull out of the film business all-together, they cannot possibly expect that MORE films are sold when the price is increased "substantially"....?

I got around 45 rolls of Acros 120 in the freezer and have bulked up on Acros/Neopan in 35mm and I fear that my stash will out-last Fuji's commitment to film, seriously.
