I have been keeping up with what authors are saying about the EU, and yeah, post-Endor is basically gone. In December (or earlier, apparently) we're going to have an entirely new timeline for the post-Endor world.Timothy Zahn (also known as "the writer that created Thrawn") is my favorite EU author by a fairly large margin; although a lot of things would need to change substantially, many of his characters and possibly even some of the events in the Thrawn trilogy could survive in the new timeline. One of the reasons that's true, though, is that compared to the Vong invasion and the New Jedi Order they're set relatively close to Endor.But if you think a massive invasion by a group of improbably capable, extragalactic, sadist Luddites counts as a "fine detail" that can reasonably coexist with the new movies, then... honestly I don't know how to have a conversation with you, if that's the case.No it didn't get wiped.Post Endor got wiped. The original Solo children no longer exist, Vong are gone. We don't know what's coming back. I imagine Thrawn will probably be back in some way, shape or form, but NJO, Legacy and Fate got paved over. It's pretty much the entire reason for the canon change. In Canon, post Endor is a mist right now.It doesnt overwrite anything. Besides the writters have already said that if anythings changed it will only be the fine details.
Ill begin with your Zahn interview link. That's not where I got my information, if it were you would have sen him say he was going to repair any conflicts of information if it pops up.
Also you might have missed th artical from one of the rebels writers saying that the old eu is still canon as we'll as these articles.

Also as waspointed out in another forum the way old eu is now treated its 2ndary canon type 1. It doesn't need to b refrenced to be canon, but can made none canon by contradictions. Also going by what authorshave said, it would oonly be the fine details tha are noncanon. Old eu if refrenced becomes primar canon like stuff including the emperors true throne world from dark empire being used in the tarkin novel. Also dark empire only takes place 6 years after rotj while ep 7 takes place like 30.
