I doubt we’ll ever get an official release of the 2005 ROTS. It’s just too close to identical to the BR release.
For AOTC, the 35mm version would be a possibility, as would the IMAX cut, but I doubt they’d make a distinction between the DLP and DVD/BR versions.
Then there’s the question of TPM and the OT’s “middle children” (2001 TPM with extended scenes and CPY; OT 97 and 2004), which are possible, too.
It’s more likely IMO that we’ll get the original theatrical cuts sans ROTS (77, 80, 83, 99, 02 [35mm]), and the “final” cuts of all of them alongside (2011 BR versions), with all the middle versions omitted. With the IMAX AOTC possibly thrown in for good measure.
