We can hope for expansions and overhauls, but we won’t know anything until it’s “confirmed” by one of the insiders on here or until Disney randomly drops an announcement to combat something Universal May announce or wait until Destination D.
Yeah, it's important to keep in mind that this was one of the weakest announcements ever made by Disney regarding the parks.
This
(all of it) has less of a chance of happening than the Spaceship Earth redo, the Play Pavilion, The Main Street Theater, etc.
Just a reminder, those were all announced as
actually coming.
These other things, announced as Blue Sky concepts, were things that didn't exist other than a few pieces of concept art. It's safe to assume anything not shown in that art, including the majority of that boat ride, doesn't exist as plans for size, spacing, show scenes, etc.
It can take years to actually design the attractions and spaces/lands that they are supposed to go into and then you have to think about Disney's construction timeline and that's all
after they get approved, which, as far as we know, hasn't happened.
But even if green-lit, it really means nothing until we start seeing work done... and even then, if recent history is any tell, work starting doesn't necessarily mean anything, either.
They
started on Play, right?
These D23 announcements were made specifically because they
didn't have anything to announce.
It was a way of making nothing look like something.
