Yeah, Pro 160NS is the latest version of the film that used to be known as Pro 160S and, way back, NPS 160. It has less saturation and contrast than Pro 160C, which I believe doesn't really exist anymore.
As far as I can tell, it's only sold in Europe and Japan...but I'm hoping someone knows a place in the U.S. where I can get it without paying obscene shipping costs or VAT.
Fuji 160NS is freely available in China. I saw many boxes of it this week when at the film store.
