Do you think they toss out the Zahn series?
oh I don't know, but as soon as Episode 7 hits theaters, everything that was written or made as a follow-up to Episode 6 is invalid.
all the books, all the comics, all the video games that chronologically took place after Return of the Jedi, all of it means nothing. its all "alternate universe".
the expanded universe will have to be completely recreated after whatever the last movie ends up being.
