Star Wars’ expanded universe (EU) — the extra, non-film material that’s plagued/intrigued the fandom over the years is to be pushed aside for the new feature films that Disney is making:
In order to give maximum creative freedom to the filmmakers and also preserve an element of surprise and discovery for the audience, Star Wars Episodes VII-IX will not tell the same story told in the post-Return of the Jedi Expanded Universe. While the universe that readers knew is changing, it is not being discarded. Creators of new Star Wars entertainment have full access to the rich content of the Expanded Universe. For example, elements of the EU are included in Star Wars Rebels. The Inquisitor, the Imperial Security Bureau, and Sienar Fleet Systems are story elements in the new animated series, and all these ideas find their origins in roleplaying game material published in the 1980s.
Demand for past tales of the Expanded Universe will keep them in print, presented under the new Legends banner.
On the screen, the first new canon to appear will be Star Wars Rebels. In print, the first new books to come from this creative collaboration include novels from Del Rey Books. First to be announced, John Jackson Miller is writing a novel that precedes the events of Star Wars Rebels and offers insight into a key character’s backstory, with input directly from executive producers Dave Filoni, Simon Kinberg, and Greg Weisman.
