YOu're assuming stories in "that universe" would continue. And if they do, the books themselves, which already happens. Unless Episode VII is an EU movie, it is going to change things. As soon as you need start "retconning" thing, espically things like Chewie being alive, Lukes love life and children, Han and Leai's children, the status of hte galaxy etc..... Its not connnected or consistent anymore. The new movies will already "destory" that. So you don't want constant retcons and reboots, but you want them to do that to the STar Wars EU The best way to go is to create a new, freash, clean continuity around what Episode VII does. That fixs just about all the issues you seem to have.
