For months - years, in some cases - Disney has been talking a good game about new and upcoming major changes to the parks. Bob Iger and Josh D'Amaro have reiterated their stance, at every opportunity, that major parks investments were coming in the next decade, to the tune of $60 billion. This was exciting news for Disney fans! Disney (the corporation) has been focusing most of its attention on streaming and other related media, including how to handle Hulu and ESPN. But it always remained true that parks was its most profitable sector, and things seemed to be turning back in that direction.
The question was more about "when" than "if", though even that had some caveats. Disney has officially announced things in the past that end up not happening. So you'll forgive those of us who were in "wait and see" mode when some of these blue sky concepts were being thrown around at the last couple of D23 events. Looking back at what we wrote then, so much of this seems very speculative, perhaps as a way to keep fans engaged and looking to the future while Universal charged ahead with Epic Universe.
