Pro 160 NS is still in the Fuji film programme. And easily available from the bigger distributors.
So far there has not been any discontinuance statement from Fuji.
Excellent film by the way. Has the best detail rendition (highest resolution, finest grain) in its class. And very precise, natural colours.
Like RarryMouse said, any film that didn't get updated Fuji packaging is on the way out. Even if it's still around, it's time is numbered. Time to stock up while we still can.
