The big question he posed is this: will the fans eventually agree on a definitive "preserved" version? I'm not talking about what I would call restoration, i.e. fixing effects, jump cuts, etc., but a version exactly as the original (well, with options to select original or 1981 opening crawl, and mono, Dolby or a remastered sound mix).
I optimistically believe that since the quality is constantly improving, there will eventually become a time when the law of diminishing returns applies, and we have a version that represents the best possible transfer from the material that is available.
