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.
