I think the best we can hope for the PT is more or less what we're getting: marginalization.

It's never going to go away, and we'll have to live with aspects of it, some more obvious than others, but Disney doesn't seem to be going to great lengths to force prequelisms into their current content.

That doesn't mean they're going to great lengths to ignore the PT, either, and it's definitely acknowledged when it comes up, but they certainly aren't shoehorning references to the PT into every piece of content they produce now.
