The change over from Disney-MGM Studios to Disney's Hollywood Studios began today in a very low key manner. So far, only the signs at the entry area have been switched over. All signage outside the park, and the vast majority of it in the park remain unchanged and still display the park's former name. most surprisingly, no Disney's Hollywood Studios logoed merchandise has been spotted so far, and old Disney-MGM Studios merchandise is still available. The parks main gift stores are selling the generic WDW merchandise in place of the park specific items.
