I don't buy the "easier global travel/internet makes it easy to get information" argument for why WS needs to change. To me World Showcase isn't really meant to be a replacement for the real thing, but instead a way to introduce people to a bunch of other countries that they may not have been motivated to research or travel to on their own. So it's not a case of "I have no other way to learn about China, I have to go to Epcot", but instead the Disney name is attracting people to Epcot where they may discover that China is an interesting place, and then they can use other means to learn more about it.
