Have you ever considered that some people might buy the books even knowing they're not canon? I foresee a whole hipster SW movement. "Pfft, Sequel Trilogy. These old books are much cooler." But yeah, I agree with the others. No way any book store is going to complain about this. Do you seriously think that the executives at Barnes & Noble (or, say, Waterstones for my fellow Britons) are sitting round a table going "#@£%, Episode VII is going to remove these books from the main Star Wars continuity. We have to get a major Hollywood studio to change its plans now!"?
