Rteez, You gotta get out more...heck, Easton Town Center in Columbus, Oh has been doing this already for 20 years
...and there are multitudes of these type of places in your metro Mid-Atlantic and Southeast areas (aka, find a major mid-atlantic and southeast city and look right around their suburbs and you'll see acres of these types of places with gorgeous fountains/water features, kid play areas, high end stores, themed restaurants and high end restaurants, entertainment, etc)...it might be new for Disney, but not for most Americans in the midwest/on the east coast...
Now, they are popular right now, so that should help Disney...as will EPCOT's current state, b/c as someone posted before, I think people will start to skip EPCOT entirely and do their food touring here when there are no festivals...
