Iger was the one that solidified the rumor that the name was definitely going to change.
After a disastrous survey of possible names, all horrible, the Internet was aflame with hair. Disney Park Blogs then said the name was not going to change.
I and others have been making the argument that "studios' fits in the sense of production companies that Disney owns (film, animation, Pixar, LucasFilm, Marvel, etc...) rather than a studio lot where films are made. The "Hollywood" in the name is the theme of the public spaces, the locale of Hollywood and L.A..
