World of Disney is getting a complete remodel - outside/inside. It's meant to make it more modern and to fit in with the rest of DS more (i.e. Less theme, more generic). Think Uniqlo in terms of what the new World of Disney will look like.
Large portions of the store will go down at a time for the refurb, so Disney is going to be opening up a second World of Disney store in the large vacant building in Town center to move merchandise to while the store is under refurbishment. The relief store will be called "The Disney Corner" and is located directly to the left of the escalators once coming out of the Lime Garage, across from The Polite Pig.
