You don't rename a park that has that kind of gravitas behind it's title. I'm guessing it will remain Epcot. They haven't pushed that as an acronym since the 80s, and it's a name that is known around the world. For the same reason, I expect DHS will continue to have "Disney" and "Studios" in the name.
I don't question the name remaining "Epcot"! That's not the point of my inquiry. Per insider info a rumor suggests it will be renamed or gain "Center" making the rename either "Epcot Center" or some variation of that. With the new Spine being built; it seems Disney wants to "change the look of the park" but my question is Why? and what's the point?
It seems pointless to rename the park or even redesign the spine unless there's a larger goal in mind; a possible rebrand. That makes sense. EPCOT has failed and "Epcot" is also failing. It stands to reason they want to fix it any way they can. A new spine, a new name, those would play a part in renewing Epcot as does the adding of characters and IP'd rides; essentially turning the park into a Magic Kingdom 2.0. But what will Epcot eventually become? What's the end game? Clearly Epcot is changing. Into what we don't really know. Is it unreasonable to think the lands within the park might also change names?
With regards to the Spine specifically; what does this design signify for the future of Epcot. Is it's purpose just to tidy up the park or is it a part of a larger plan for Epcot?
