I don't even think a solid D23 showing is good enough at this point. They need results, they need their stuff to be as widely praised as Fantasy Springs. They can announce as many generic 2010s and beyond IPs being added in rides and "immersive experiences" announcements as they want, but that won't change that the hardcores (at least the type that would go onto a Disney forum) are too jaded that any announcement is thought as never actually getting made, going to be far reduced in scope compared to what is promised, or is simply going to be so corporate boardroom planned that it's making the base attraction or overall parks worse.
Trust in Imagineering is real low to accomplish anything promised in these media events, and most don't even want them to touch things that need revamps. That's a serious issue, and one that more promises to the media isn't changing, only those announcements living up to standards when opening regains trust.
