No doubt official discontinuation will come when it runs out in Japan.

Thoughts on whether fujis final profession CN film - Pro400H or Portra 160 is a better substitute?

If you print in the darkroom then 400H is a better substitute as it prints on the same filter pack. All the Fuji pro line (C, S, H, Z) were designed to print on the same channel.

Yes, stock up now if you like it along with any color or slide film.
