Yes but I wouldn't be suprised if they do a bit of redesign and make DHS better reflect the Hollywood of the 40's and 50's as rumor has it DCA's redo will likely reflect the Hollywood of the 20's and 30's. I could easily see them redoing RnRC into a tribute of the early days of rock n roll as Aerosmith will sooner or later become passe.
So then that whole expansion area between ToT and RnRC could be the Hollywood of the 50's and early 1960's (hmmm, maybe even something themed to the great movie "American Graffiti"???)
From wiki---- The film was nominated for five different categories at the 46th Academy Awards, and in 1995, American Graffiti was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress, and was added to the National Film Registry for preservation
