I guess I am the rare one that says perhaps in the 2020s it is built. The reason being is that Disney has got to be a little worried about Universal now. Epic Universe is going to be....................well, epic, when it opens in 2025. Disney always has an answer for things Universal does. Universal opened in 1990 in Orlando, and in 1989 Hollywood Studios opened. Was that a coincidence? Nope. They were trying to get ahead of it all. I think a 5th park could be built if they wanted to do it. They have the space. They have to bring in some new blood, like some old school blood, ones that had imagination and creativity. The old Disney way. This new modern way of cheapening current rides like Splash and such is going in the opposite direction. Honestly, when Disney says it wants to "re-imagine" a ride it just makes me cringe. Because you know it is only going to be inferior to an already great ride. So they need to change their mindset with this. Universal is literally even with Disney in park attendance when you take away Magic Kingdom. Seriously, at this point there are as many people going to Universal per park as Disney. Only Magic Kingdom separates it all as no one reaches their attendance. That's a slim lead.
