Read what I said very carefully. Let's say that, post Ep VII, a new novel comes out set in the Rebellion Era. Will LFL (a) say that the "pre-ROTJ EU is strictly canon and you must adhere to it" (b) say "Make sure you don't contradict the OT, otherwise do what you want" I assure you it'll be much, much of the latter than the former. Also, the character prequels aren't rumors, only which characters and in what order. I can guarantee that they'll be doing pre-ROTJ material in there.
