The new issue of Tales from the Laughing Place
has an interesting article on the creation of Tokyo Disneyland (and a bunch of never-before-scene artwork).
In it, Joe Lansizero (head of WDI for TDR) said some interesting(disturbing) things about the future of DisneySea. The gist is that in DisneySea, WDI built ports that were too specifically themed (i.e., 1932 South America, 1912 New York City rather than Adventureland which spans the globe (Caribbean-Tahiti) and centuries (1700s-1920s), and this is making it challenging to add entertainment/attracions in ways they deem desirable
to most park-goers.
Joes says: "We haven't thrown the themes of TDS out the window, but we have had to take a more lax view. We have to infuse more characters into the park, but they still need to be appropriate to each land."
This means Pochahontas in the American Waterfront and Hercules in Mediterranean harbor.
With respect to Turtle Talk, it sounds like it may not be as bad as I had initially feared (although time will tell). Joe said they are going to try to keep it somewhat time/place appropriate (an old-fashioned hydrophone will be used and Crush will not be a surfer dude (stereo-type doesn't exist in Japan), but a fun-loving dad).
