For my purposes (meaning: to sync to the GOUT), all I need is audio in the best possible quality. No video required, no sync of any sort required, no commercials edited out, etc. I’m willing to wait for the whole trilogy, though, it’s not like I don’t have plenty else to do in the meantime.
If, however, there are subtitles to cover things like the crawl or alien dialogue that they opted not to dub over, then I’d need that text. Screenshots or transcriptions are fine, video isn’t required.
