From what I remember, Dave Bias stopped posting around the time Film Ferrania decided to engage less with forums and social media....again, due to threats, insults and abuse from people who accused them of fraud, lies and worse.....people who don't understand or didn't read the Kickstarter....believed they had ordered film and got angry when they discovered that what they'd actually signed up for was to donate towards saving equipment to manufacture film.
From what they've said, I think they are concentrating on B&W as it is something they can now reliably manufacture and actually brings in funds. P30 was an unusual film, one I happen to like in certain circumstances. P33 seems more "general purpose" and I've not used it yet but have seen some truly lovely photos taken with it. There was a rumour they were going to release P36 too (320ASA) but that hasn't happened yet. They did mention a good while back that research was continuing in the background on colour film. But as they have consistently stated in recent years, they are only going to release news when they are ready to share a product with us.
That strategy is supposed to put an end to the entitled folk who cry and scream about Ferrania being crooks every time this small company misses a target that was always aspirational rather than realistic....or when the Italian government cuts their campus in two and turns off the gas and electricity.
Thanks for the summary Gulliver
