I went from being hyper jaded and disinterested in Star Wars since 2006 or so to being fully back in and incredibly excited for these new movies. I even went and picked up the Darth Vader and Star Wars Marvel comics.
they've said that they will borrow concepts and rework them at their leisure. even if it isn't the exact thing outright, it will be similar. or they could do a direct lifting and that would be fine too
I don't have the quote but I remember reading someone saying that they may pick and choose some Legends elements but it seems very doubtful to me that whole old EU stories/products will be brought back into the canon.
I've been going through a big EU binge recently, I guess as a last hurrah before TFA comes out, and while a lot of it is fun (mostly Old Republic era stuff), it's striking how awful most of the post-OT era stuff is. I like a lot of the general concepts and want them to hold over, like Thrawn and imperial warlords like Isard and Zsinj all claiming their pieces of the pie, the political crises like the Caamas Document Crisis, even the concept behind the Second Galactic Civil War. But then there's the Vong, and Waru, the entirety of Legacy, Triclops and Rajah Ubooki, the Darksaber, Callista Ming...
