It is completely, absurdly out of place. It clashes with every other element in Future World. That's why folks believed it had to be connected directly to Seas - it was the only way that its placement could be even loosely justified.
It will become another of EPCOT's many big, empty, pointless spaces, joining Odyssey and the Millennium Pavilion and Play! and the end of Imagination and etc. etc. The only difference is that this space is outdoors.
And we can make a very good guess as to its life cycle - WDW management will very quickly tire of paying for staff and upkeep at such a pointless attraction, one that doesn't move merchandise and likely won't make much of an impact on guest satisfaction or significantly dent park-wide capacity. It will be a meet-and-greet within two years (if it isn't at opening) and roped off within eight.
It's primary function is as a monument to the horribly dysfunctional development process that fueled the much-needed EPCOT redesign - the complete and overwhelming lack of vision, the indecision and second-guessing in the board room, the absence of efficient practices, the clash of CEO egos, the unimaginably over-inflated budgets, the comically self-aggrandizing PR, the ham-handed insertion of IPs. The development of "new" EPCOT would make a very funny Office style sit-com with little embellishment, and Path of Water is the punchline.
