As a huge fan of the EU, particularly all the novels... I think they SHOULD reboot the continuity.
We've had, what, 75 novels to tell the post ROTJ story now. The Big Three are pretty old at the point of the novels now.
Only thousands of people have read the EU novels. Millions will see the Sequel Trilogy. There is no way in hell that the makes of the Sequels will, or should, be beholden to the old continuity only a few know about, which was conceived in the 90s before we knew anything about the Prequels.
I'm looking forward to an entirely rethought post-ROTJ continuity, one more closely in line with the movies (read: less Empire Remnant Super Weapons, more Dark Siders).
