Like I said in another thread:

If the leaked plot rumors are true, then I'm glad they're justifying the jettisoning of the EU by going in a totally different direction. Since it's been 30 years, I can kinda see why they got rid of everything. I mean, it actually would've been harder to justify titling your movie "Episode VII" when you've got 40 years worth of epic shit that's happened in the interim.

Yeah, it's awkward that they kept that continuity going for 20 years only to throw it out now, but part of this is due to Lucas' fickle nature. As of October 29, 2012, Episode VII was still "never gonna happen," so it didn't matter to Lucas what they continued to do in the EU. RotJ was "The End" so far as he was concerned. The Thrawn Trilogy onward was "the rest of the story" to satisfy the fans. Now Lucas has changed his mind.
