It seems to me that Epic is the perfect storm to finally put chemical film out to pasture, in much the same way that high-end DSLRs did over the last few years for stills. It will shoot a "real" 4K, RAW, s35mm, cine glass, overcranking onboard, solid-state or harddrive recording, etc.
The ONE THING Epic needs to do in order to fulfill it's destiny, though, is match (or come close to) chemical film's dynamic range. Aside from nostalgia, DR is really the last leg film is standing on right now, IMO.
Similar to Clinton '92's precept "It's the economy, stupid," the Epic team should have a poster on the wall reading, "It's the dynamic range, stupid." :weight_lift:
With a sensor upgrade next year, I think Red One will do the same.
