George R. R. Martin recently announced that that he was going to be at a fan organized event on January 9th in LA. He also stated that he might have one or two really exciting announcements that day. Now I don't want to get anyone's hopes up, but assuming that the rumor we talked about earlier is true, this could be the announcement that A Dance With Dragons is finally complete!
Obviously this is just guess work and should be filed firmly under 'rumor' for the time being, but I for one have a really good feeling about this.
Keep your fingers crossed!
