First of all, USAToday is barely a newspaper, IMO. It's a collection of puff pieces for the most part. This article is no exception. The reporter was fed the facts and he did what he was told, like a good little puppy.
You know, we've been talking here for a long time about what would be an effective "Potter swatter" for WDW. Most of us agree that Avatar sure as heck ain't it. Nor is Star Wars. The main reason is that NEITHER have that Disney connection in the public's mind. Remember, DCA in Disneyland didn't succeed in large part because - in Robert Iger's own words - it wasn't "Disney" enough. (The guy's a hypocrite, though - he says that, then buys the rights to Avatar to shoehorn it into AK, while ignoring the possibilities of home-grown product like The Lion King and Jungle Book...but I digress).
But now, Disney may have that "Potter swatter"...in Frozen. But it all depends on how ambitious Disney will get about it. Whether it will build a major attraction, or major area, or just stick with the meet-and-greets.
Sadly, it'll probably be the latter...
