I think that a decision to rub out the existence of Mara Jade, Jacen, Jaina, Anakin Solo and Ben Skywalker would be a giant middle-finger to the Star Wars fan community.
Outside the little group of "Original Trilogy Only" die-hards on this and other movie-oriented forums, there is a great community of Star Wars fans out there who have embraced the dozens and dozens of books that have been published since the Thrawn Trilogy.

But you know who doesn't care about the EU? My mom, and the millions of other people who want to go see a Star Wars movie and never did and never want to read books to get the full story from a movie series. The ST will be designed to sell tickets, and making sequels to various quality books based on movies is not the way to do that.
