I agree. There's no reason for Disney to add new changes, whereas with George, tweaking the films became a self-contradictory, personal crusade. I reckon we're now stuck with the 2011 editions as the "canonical" ones.

From a business perspective, it'd actually make more sense for Disney to redact some of the more recent changes; would a casual fan who's happy with the 2011 Blu-rays care who shoots first, or whether R2 hides behind a rock outcropping? Probably not, but I'm sure removing the most egregious SE changes would have a few more die-heards reaching for their wallets...
