That's what they get for so barely changing it, I guess. I agree it's a silly error.
Does it irk anyone else that the "Neighborhoods" are listed in such a weird order? World Discovery, Celebration, and Nature mingle so closely . . . and are so clearly the mere result of the dissolution of Future World, that it's strange to pop World Showcase in the middle. World Showcase is clearly more substantial . . . seems odd to list them in a way that suggests they carry any sort of equal weight.
Not to mention that there's simply no relative flow to the information that makes sense when reading the map - at the very least the listing should have been:
World Discovery
World Celebration
World Nature
World Showcase
. . . since that at least somewhat aligns with their relative positions on the map.
FAR from my biggest issue with the EPCOT redo, this is just a quibble . . . but weird nonetheless.
