I am not nearly so certain. The Star Wars property has not only been abandoned for twenty years, it has been actively scrubbed from the cultural memories of younger generations using an audacious bait-and-switch tactic. I'm not saying Disney won't do it, but the math isn't entirely in the favor of doing it. And the longer they wait, the less reason there is, as the actual Star Wars fanbase dies off, replaced by people who know only the Special Editions, and are only vaguely aware Star Wars existed.
And even if they do, I'm not sold on Disney's ability to do a respectful restoration, given their existing Blu-ray catalog. My guess is, if it's ever released at all, it'll be the 1981 video for Star Wars, and the 1993 audio mixes for all three films, possibly given some new surround remix on top of the already non-theatrical audio. Would they replace damaged footage with Special Edition footage, hoping nobody notices? Will they ship it off to Lowry to re-do the damage they inflicted in the SE's? There's a lot of ways this can go wrong, and without someone who actually deeply cares about the films in charge, I can see any of them happening rather easily.
Of course I'd love to be pleasantly surprised, but after waiting so long for a Blu-ray quality release (or, hell, I'd be happy with a DVD-quality release, rather than Laserdisc-quality-on-a-DVD), I think it's safe to say I'm jaded.
