I somewhat disagree overall. Yes this new trilogy will be original and will introduce a new cast. I also believe it basically close the anakin/luke story as we currently know it. However with Disney, I could see them eventually with the right scripts putting movies and other media projects forward that use the EU as inspiration. We can't have things like the thrawn trilogy now because the original cast is to old to make it believable and we as fans want the original cast to be apart of this in some way. However once this new triology is complete with the handover to that new cast taking that part of the story forward, I could see disney come in down the road with a rebooted "original cast" and do some of those projects like thrawn or something based off of thrawn.
