Or they could just do what Trek does, and completely disregard everything that's not the movies or the series. Close to NOTHING from Trek novels - not even the novelizations of the movies - is considered canon, nor is anything from video games. Likely because, more often than not, those things conflict. We've had several books that have featured Vulcan, and they're all drastically different both from not only the canon, but from each other, too. The major difference between Star Wars' EU and Star Trek's is that Star Wars' is a lot more structured, so that there ISN'T constant retconning or multiple variations of stories in the same time frame. Granted, the release of the prequel trilogy kinda messed things up a bit, but nonetheless.
The trouble with "dumping the EU", though, is the fact that, without it, there would frankly be no Star Wars fandom, as the best stories and characters have been EU creations - or original movie characters with expanded stories in the EU (i.e. Han Solo). If there IS to be a new trilogy, despite what they've said, they HAVE to take the EU into account, or there will be fan outrage the likes of which have not been seen before...and frankly, Lucas would not be this rich snob he is now if it weren't for the millions of loyal fans (including the many thousands of complete zealous fanatics...i.e. the ones who go in costume).
