The GOUTs were only released individually at first and didn’t get a box set until the 2008 sets.

Since you put it that way, I noticed one set of covers for the GOUT has a banner that says: Exclusive Bonus Material! Includes 1977/1980/1983 Theatrical Version Available For Limited Time Only!

And another set with a banner that says: Limited Time Only Includes The Digitally Remastered Movie Plus The Original Theatrical Version

Is the former the initial release and the other a re-release that came out before the 2008 set?
