Sure looks like it to me. He just posted great-looking images of Greedo w/ original subtitles and Mos Eisley (and it is a GOUT-only shot, ddonna, this is NOT a hoax). The color balance reminds me of what I've seen of the Senator print.

Hell of a lot of detail, sharp as s***, it has to be a film print. He also said that he's not using telecine, as the quality is not sufficient for what he's doing. He previously referred to his image of the SW logo as being 4K. Take from that what you will.
