GRRM did mention at last nights meal that he had been working on D&E Part 3 but wrapping it up wasn't as easy as he hoped. But he is close. Originally it took place right after tSS but now he has decided to give it a 1.5 year gap but that means another round of mods to ensure the timeline works. (A 1.5 year gap makes sense to me if he wants to continue to progress Egg's story up to and beyond him taking the crown). He also reminded me of the state of the Starks 100 years ago...
SPOILER: Starks 100 years ago
I was suggesting it would be nice to see the Starks in power, without the current disarray. But GRRM pointed out that things were not so good 90 years either, with a lot of Stark widows struggling for power, with the current lord dieing from a wound taken against some Ironborn. Although I could have the reason for his wound up. I'm reading the RPG game book at the moment and I might be mixing things together. There is a lot of Stark kids around though, so ending the line wasn't a problem. I think he said 10 children, from various Starks members.
Oh, and I don't know whether the Starks are actually going to feature in the next book. It does seem like he has an idea about a Stark story though.
Anyone remember what he called the Stark widows btw? Wolf crones or something?
