Guys,
You should remember that the Ferrania project wasn't just "making slide film". It's not as if Ferrania had a working factory and then they decided to make slide film. If, for example, Foma wanted to make slide film, it would be rather easy for them, provided with the necessary investment to unlock Photo Engineer and treat him with the necessary spoiling so APUG members don't travel en masse to Bohemia,CZ and start a riot on the Foma factory.
Ferrana had to basically create a new factory, and additionally it needs to plug this factory into the power grid, water supplies, etc; due to external circumstances. They also had to refurbish specialized machinery themselves. Machinery that probably isn't available to buy "brand new, ready to use" nowadays.
I think that most setbacks have had little to do with Ferrania itself and more to do with the Italian infrastructure projects.
The fact that they were able to make an emulsion (P30) that works is a great signal. It means that their machinery finally works. Even better if they ironed out the initial coating problems. Even better if now they are about to make their own 120 backing paper. This, in particular, is a BIG reason to be happy in 2018, for it will benefit the other manufacturers too, since this specialized supply was in danger to become monopolized.
P30 might not be a fantastic film, but consider that (a) this is original film, not rebranded film made by (foma/kodak/ilford/fuji/shanghai/orwo), nor rebranded old stock film from Agfa/Svema/et, and (b) it is a distinct film, with distinct spectral response and characteristics, so it gives us a new alternative. I think it's always great to be able to have many films with very different looks, for example FP4 vs Foma 100 vs Adox 100 vs Tmax 100.
They are almost done in the "having a working film factory" task, so they are almost ready to get into the "make slide film" task.
