[Note: This article reports on Martin's trip to Slovenia, and is in Slovenian. However, the embedded video features Martin discussing the genesis of the novels and shows other details from his trip.]
[Note: This report is somewhat garbled, but we'll leave the text as is. In fact, it's not the title of the story -- it is, instead, the title of the anthology that the novella will appear in, the title giving away the theme of the anthology... and so still supporting the idea that it likely involves the Wolf Women of Winterfell.]
"Dangerous Women".
That's the title for the planned fourth Dunk&Egg novella. George said as much Friday last week in Poland. I was there. Unfortunately the other answers to questions are not that revealing.
[Note: Though the interview concerns the television series, GRRM makes a number of remarks related to the sexuality of characters in the series, and his approach to same.]

George swore that if he was ever going to consider doing another cameo it would involve sitting in a chair, preferably with a large drink in hand. The life of an extra, standing hours in costume during dozens of takes was not high on his list!
One bit I found amusing was talking about creating names for writing. George first did a brief rundown on English names during the middle ages. Essentially a few simple names dominate. If your name wasn't Henry, Edward, or possibly Richard, you weren't going down in the history books. Then he talked about hearing interesting names and keeping those for future stories. He said when watching the NFL draft each year he picks up a couple of neat names for future use. Now I won't be surprised when Ser Ochocinco pops up in book 7...
George did mention you a few times Ran, He said he thought his hearaldry was pretty awesome until you actually produced them.
A few of the interesting bits that I recall off of the top of my head were some questions about the heraldry and armour. Westeros has better technology with dyes, than Medieval Europe did. Thats why they are able to great consistent colors such as scarlet, crimson, or burgandy rather than just red. Also they have ways to enamel or infuse colors to armour which weren't available to medieval smiths.
During the first Q&A someone asked if he had plans if he was "unable to finish the series." George asked for him to be stripped naked and be tossed out in the snow. :P He then said well at least you didn't say "pulled a Jordan". He actual did go on to reiterate he had no plans, but that if he were in a sitation like Jordan, he could forsee making contingency plans.
Then during the HBO Q&A he was asked what would happen when the TV show caught up to his writing. The audience groaned. George asked for this person to be stripped naked and tossed in the snow. He did say he felt he had a pretty decent head start, so hoped it wouldn't come to that. He also said that if something should happen to him , that David, and DB do know how the series ends. That was news to me.
The other bit of news was that at one point George tossed out the phrase 7 or 8 books in the series. I had not heard mention of a possible expansion to 8 books before.
