Yes, we are moving to theatrically sync all three films from this point forward. 4K77 2.0 and 4K80 1.0 will include all available frames even if they were missing from the NTSC (or PAL or both) GOUT versions.
Presumably, however, we will continue to ensure that the Star Wars logo appears on frame 689 as it does on the GOUT, so that all the audio tracks still have the same starting point.
