Have you seen anything official in this regard? I imagine this is likely going to be the case at some point, especially as 160NS doesn't appear to have gotten Fuji's updated packaging, but it's still readily available here.
It's still available in EU and Japan. It's days are numbered for the reasons you have mentioned. I'm off to Japan in 2 weeks and I'm going to stock up on it + neopan 400.
The great thing about fuji in 120 is that I don't have to lick them. Also I do like the subtle and muted colours.
