But now they're not even canon with the new canon. So, things could be changed on a whim. We now have two different canons. It's like old EU is Earth Prime and new EU is Earth Lucas, and Infinities is Earth Wat. It's going to be a hellish, confusing mess.
And then there's the possibility that Disney will actually delay establishing a solid canon, with all the old EU up in the air. We also can't be sure how things will be referenced. Mara Jade could be name-dropped, but her actual character left vague. Is she a former Emperor's Hand? Is she a waitress?
What about Kyle Katarn? Most Awesome McBadass Powerfist Jedi ever, or a gas station attendant?
Grand Admiral Thrawn. A Chiss Grand Admiral who is incredibly arrogant and a master tactician? Or some homeless guy with schizophrenia?
Granted, they weren't g-canon, but they were still canon, something that I further confirmed during my visit to Lucasfilm. Internally, the EU was still considered canon, despite the retcons needed from TCW. Leland Chee's entire job was to oversee the entire canon, including the EU. I've seen his Holocron, I've seen the archives, I've seen stuff I've NEVER seen that was still considered to be in canon.
All of that right now is in limbo. All of it.
