But being a working studio isn't just a theme, it's a reality. Unlike DHS and the international parks, both of Universal's U.S. locations are still actual production facilities, albeit not the most active or prestigious in Orlando's case.
USF technically can't lose its studio theme until it ceases being a studio, but the concept of its various lands doubling as a backlot for TV & film production has already had holes punched in it by the likes of Springfield and Diagon Alley, which have no real potential for serving that purpose. Rockit also damaged NY's potential for production, even though there's always CGI. Might as well add fantastical video game lands to the mix at this point.
