Since the 2011 Blu rays are subpar at best the SE would need a re-release too, and I doubt Disney will release it without the OOT because it would make them seem like Lucas. I honestly don't think ANYONE (fans or not) would care if they just got the OOT and not the SE. But I think you're right, for now if they release the OT it would probably still have the SE's. I don't think canon as far as SE's go is a concern, I don't think anyone is worried about whether or not it is canon that CGI green dinosaurs walk in front of the screen in Star Wars.
