Guys, we must understand what “film revival” actually means.
It means it’s a niche. A niche. Nothing professional, but craft-level.
It is indeed a niche compared to digital imaging. But it is a growing niche. And in absolute terms the whole silver-halid products market globally has a size of more than a billion dollars. So it is not a small niche.
And that there is "nothing professional" is fortunately completely wrong. There is a five-digit number of professional photographers worldwide using film. This number is also slightly increasing again.
We will never go back to shooting assignments with films. .....No magazines (do they still exist?) will ever require film images.
Both is fortunately wrong. We know of assigments shot on film, and lately even big fashion magazines (like Vogue) have published film images again. Because the film look was wanted.
It’s a craft. If watercolors still exist, film will exist. And both have an equal market.
The market for film photography is much much bigger than the market for watercolor painting. Please don't forget that the market for instant film photography alone is meanwhile a huge mass market again, even surpassing the market for digital ILC cameras. E.g. you can get instax film in the big supermarkets, or here in Germany in the drugstore chain shops. So available in about 4,000 walk-in stores in one country alone (together with 35mm standard film, by the way, and processing for C41, E6 and BW). You won't find equipment for watercolor painting in these shops.
A new film camera? Sure, in about 50 years when the used market will dry up and ressemble a landfill, a new film camera will be manufactured in order to match demand. This is no rocket science, really.
About 5 years is much more likely, if we consider 35mm and 120 film. In pinhole and LF we already have got lots of new camera models during the last years, even total new manufacturers for them have come to market.
And lots of new instant film cameras.
It even could be the case that 2020 will be the first year since 2003 in which in total more film cameras will be sold again than digital cameras. The current published data for digital cameras for 2020 indicates that this year the digital camera production will likely be in the 7.5 to 8.5 million units area (a historical low). Fujifilm alone has sold 10 million instax film cameras in their 2019 fiscal year.
