During COSine, George R. R. Martin was interviewed in a podcast by the folks over at THACO. In it they talk mostly about his licensing deals when it comes to the various games that relate to the world of Westeros (RPG, board game, CCG, etc.) as well as some of his other projects. They do however touch briefly on the deal with HBO, mostly as it relates to these other licensed deals. Check out the podcast interview. If you don’t feel like listening to the whole thing, the HBO stuff starts at about the 14 minute mark.
Winter Is Coming: Sounds like HBO didn’t quite get their way when it came to the deal for the series. Hopefully that doesn’t hurt its chances at getting picked up.
