Star Wars: Revenge of the Sith: The Expanded Visual Dictionary, a reference book in the visual dictionary style, was planned but ultimately never published by DK Publishing.
Originally, this book was intended to be the fourteenth entry in Dorling Kindersley's Visual Dictionary collection, serving as a follow-up to Star Wars: Revenge of the Sith: The Visual Dictionary. Its initial release date was set for September 30, 2013, but the project was shelved after Disney and Lucasfilm decided to delay its release indefinitely to focus their efforts on the Star Wars sequel trilogy. Interestingly, a sales page remained active on Amazon, which stated a release date of June 1, 2016. As of now, the Amazon listing indicates that the product is not available for purchase.
