Out of all the existing Star Wars material, only the six films and the clone wars TV show are now canon, and all Star Wars content (books, films, games etc.) moving forward will be canon and overseen by Lucasfilm's story department. However, new content is able to draw from aspects of the EU if it wants (i.e. Rebels). So basically, Episode VII, VIII and IX are free to incorporate elements of the EU if they choose to but they aren't beholden to anything that has happened in the EU. Thoughts?
