Yeah....Lucas threw out part of the EU for movies 5 and 6. They threw out parts of the EU for episodes 1-3. Why be surprised when they toss other parts for movie 7-9?
Plenty of things in the EU are pretty cool. I love the OR series of games, the Jedi Knight games really had quality, the Thrawn novels were pretty good.
Expecting the new movie to adhere to everything from the EU, though, is like asking them to make a new Spiderman movie and not only not tell the origin story, but to actually be in mine with current comic universe canon. 99% of viewers* haven't read all the comics, if you don't introduce concepts or characters but assume they know who they are, you won't be very successful. Either the new movies'd be set much, much later - thus making them "not eispode 7-9" - or they'd be retelling of books already written (New Jedi Order, Thrawn,...). Neither would be interesting from their POV.
Like the Star Trek reboot, I expect there to be a lot of reappearing characters, also from the EU, in similar-but-slightly-different roles. We'll see. I do understand people not being happy about it, but I don't really think there was another solution.
*This is not a deliberate hyperbole at all.
