Never, it will forever be a niche product. It doesn't solve almost any problem better than what we actually have but keep the mind engaged in the future of virtual reality. VR is the flying car of software: so amazing to imagine, so impractical in real life.
And color film doesn't solve anything that black and white film can't do. Besides, why watch film at all when you can look around the real world instead of looking at a moving picture on a screen.
Infrared film can do infrared colors, and people who need to see those colors use it and to them is invaluable, but that need is not a mainstream need. VR is infrared film.
