Source: Star Wars Expanded Universe (including games) no longer canonMany bothans died to bring us this information: The Star Wars Expanded Universe - or EU for short - is getting cut from Star Wars canon like hands get cut from the Skywalker family. In a news post on the official Star Wars site, Lucasfilm announced that only the six Star Wars films and the Clone Wars television show will be considered canon. In other words, as far as Luke, Leia, Han and the gang are concerned, there were no knights of the Old Republic, nor was the Force ever unleashed.
So if they're going to axe the expanded universe, does that mean they'll retcon midichlorians, too?
