That's already happened with the Alien Anthology, Superman, and T2 over there. This layer of OCD at OriginalTrilogy is what basically made me dismiss them faster than I dismissed George's annoying changes on top of existing changes.
I remember reading the 2004 New Hope transfer was graded using Lucasfilm's own dye-transfer of that film as reference and yet people still complained about it. Because apparently a 1993 laserdisc transfer made from a fourth or fifth generation IP is always the last word.
Cameron waited too long to make Avatar 2 (doesn't help that there's been a major backlash against the first film since) for any interest towards a franchise to maintain itself. Star Wars would run right over it if Fox doesn't blink.
