[GRRM is asked who comes up with titles for the Wild Cards series, and whether titles for future Wild Cards books will be difficult to come up with, as they are all drawn from card game terminology.]
I come up with the titles.
Yes, we will eventually run out of "card" titles. There's a scene in CITIZEN KANE when Kane is informed that his paper lost a million dollars last year. "Yes," he says, "and I expect to lose a million dollars next year, and the year after that. If that keeps up, I'm going to have to close the paper... in thirty-seven years." (paraphrase)
Which is a long-winded way of saying that I already have enough titles for another twenty or thirty wild card books, if need be. Some are better than others, mind you, but we won't run out soon.
