Here is an interesting interview with him:
Would you like to see them get a comic or a novels series? I really hope that novel is a ''backdoor pilot".With the Stealth Squadron pilots, for example, they now exist as rebels and could be some of the pilots we saw on Hoth. Or they can show up in other comics or novels (in fact, I think they will show up in a future prose novel!). There's no reason in my mind to kill them just for the sake of clearing the table. Without giving anything away, one of my new characters does basically exit the playing field but its sort of necessary and ultimately a positive and productive move.
