I think 35mm prints for Attack of the Clones and Revenge of the Sith are pointless.
Those were already shot in HD. I’m not sure if it was 2K or 1080p but those were digital.
I think an Ultra HD Blu-ray release of all the prequels (The Phantom Menace being a new restoration without DNR, Attack of the Clones and Revenge of the Sith being 4K upscales of the 1080p masters) would be the best way to preserve them but the Original Unaltered Trilogy in Ultra HD with all of the alternate mixes (70mm six track, Dolby Stereo, mono, LaserDisc) plus a new Dolby Atmos remix would what I want more.
