Here's another thing I heard: Martin only greenlit the post-book GoT era because writing duo Benioff and Weisz figured out Jon Snow's parental lineage. And then he handed over the responsibility to Benioff and Weisz exclusively. No other writers allowed contractually.
You're right, though. Unless HBO's legal team fucked up monumentally this all sounds rather unlikely.
Hm, bearing in mind that in the books there's already another Targaryen, I'm not so sure about that. Maybe in the books Jon will be truly a bastard, Ned's bastard or even Robert's, or who knows... The books mention a woman called Wylla, from Dorne.
And honestly, if the books end up being something similar to the show, I will be VERY disappointed.
