I agree with you David. I think he might have been talking about where he would personally have focused RED's R&D resources at the time when that video was shot. I think it is pre M-X, if I am not mistaken. Besides it is a pretty safe assumption that he really appreciates RED's high MFT at 2k, which comes from a properly down-converted 4k image --especially knowing he was considering shooting portions of Che on 65mm film. This is my point. Red One Mysterium is a camera that can deliver footage that feels a bit like 65mm in terms of detail. Now RED makes a camera that can deliver even higher MTF than 65mm, without any additional costs.
It is still up to the artists to know when and how to use resolution, as well as all the other layers of the medium. There is no excuse when you can drop a filter, apply additional softening in post, use soft lenses... etc. What matters most is the people behind, not the camera; and oddly enough that is exactly why RED's versatility is so important to me. RED gets that, evidenced by 120fps 5k, 300fps 2k, heaps of single-exposure DR, HDRx, tracking from HDRx, size, weight... cost!
Thank you RED. Can't say it enough. And thank you Steven for motivating RED so much (more) with "Che".
