One thing you have to remember. Sure, the stories will likely be non-canon anymore. But you can sure as hell bet that Disney will do whatever it needs to do to keep the trademarks on all the characters, ships, planets, aliens, etc established in the EU.
Yes, i think so because it would piss off a lot of nerds if they completely threw overboard every author has written under license. Thereare so many locations and a ton of Characters in the EU that are already in the heads of so many fans that in my book it would be a huge failure on their part to go around and just tell us what of the things we like we can have and what we will simply need to erase from our brains.
Such a steamroller diplomacy is just the dumbest thing they could ever do. I just hope they realize that. They will need to adapt some stuff to have a good story to tell. But if they are clever they will not just push the delete button on everything we know.
