So what we know from Universal Studios Beijing so far is the concept art showing a hotel that would be the main entrance to the park. Attractions that are likely to be featured is Jurassic Park, Transformers, King Kong, the Mummy, Harry Potter, Dr Seuss. It would likely incorporate themed areas from Singapore such as Sci-Fi City, New York, Shrek, Madagascar, Ancient Egypt, and others.
Popular attractions that would not be included are those based on Marvel Comics characters, as Disney officially owns Marvel since 2009 and no Universal theme park has its presence in China unlike Disney parks in HK and Shanghai. Nintendo properties are not likely to be included in Beijing (due to the country's lack of interest in such properties) anytime in the future.
