GRRM’s official site has been updated with a news item concerning the 17th Wild Cards novel, Death Draws Five, written by John J. Miller. The book has been scheduled for a January release in hardcover. More information regarding the novel can be found on the news page, as well as in this entry, which includes information concerning how to buy older volumes of the books straight from John. Also updated has been the "From My Readers" section, with a new entry in ASoIaF-inspired baby names.
For those who are really big fans of the series, it should be noted that John has been posting at the ASoIaF board, in the Other Authors forum, where he’s happy to answer questions.
