Curiosity: Film cameras and even super 8 are enjoying a revival

As I reported on Mirrorlessrumors (here, here and here) the market for film cameras are booming. So much that for example my Mamiya 7 had a plus 50% raise in value. I am not sure yet but I think also Olympus film cameras are highly requested. Sometimes I wonder if it would make sense for OM Digital to make a new modern film camera again. And Panasonic could even think about making an L-mount film camera or not?

Or is all of this just a temporary hype?
