For all the people who wish the EU to be destroyed, you will be sorely disappointed. Disney would be foolish as hell to ruin or even dump the EU. Part of the reason Star Wars is as huge as it is now is because of the EU. Remove that and you will see a great exodus of fans who give up on the franchise. Disney would LOSE money. The EU will stand as is, with some tweaking here and there.
The new films have a lot of room for new stories that take place in between the events of the novels.There is no need to stomp over the EU while also not needing to make any existing work into a film. Like it or not, the EU will stay.
no they won't They didn't up and leave when lucas made the prequels and dumped all the EU stuff. They are not going to leave now. Especially if the new stuff turns out to be good.
Remember less then 1% of the total Star Wars fans have ever read a Star Wars book.
