Even if they ultimately trash the continuity of the Expanded Universe I hope they at least borrow heavily from its best ideas.
The biggest problem with the EU is that it's so uneven. While some stuff (WEG books, Thrawn Trilogy, etc) are great, some other stuff is absolutely pathetic (here's to you, Kevin J. Anderson). And at some point it gets really hard to extricate the good from the bad.
They already threw away a lot of great EU stuff in the prequels, I think it would be a mistake to try and bring the EU back in at this point. I would happier if they formally designated alternate canons for different real-world era. There could be Original Trilogy Canon, Prequel Canon, and Sequel Canon, all with their own Holocron levels.
