Universal Orlando officially announces Harry Potter expansion
May 8, 2013

Even though construction has been happening for months and rumors have been running rampant for even longer, Universal Orlando has finally officially announced an expansion to The Wizarding World of Harry Potter, coming in 2014. In truth, the expansion isn't simply an instance of making the existing area in Islands of Adventure larger, but instead adding a new land in the Universal Studios park. This expansion, called Diagon Alley, will be accessible by the Hogwarts Express, a train that will carry passengers back and forth between the existing and new lands, just like in the popular book and film franchise. According to Universal's official press release, the "new area will bring to life some of the experiences and places found in and around London in the Harry Potter books and films, offering brand-new adventures for fans and theme park guests from around the world." It will also "feature shops, a restaurant and an innovative, marquee attraction based on Gringotts bank." The release doesn't offer much more information, simply saying that more details "will be released over time."

Most of these details were leaked back in March, so it's always interesting to compare what was leaked and what is now official. This time, they seem to mesh fairly well. Read that article here.
