From Martin's blog:

Whether you're an Ice & Fire reader or a funny book fan or both, I have cool news for you. A SONG OF ICE AND FIRE is coming to comics. Random House/ Bantam Books has acquired the rights to do a graphic adaptation of the series, to be published as monthly comics (in partnership with Dynamite Entertainment) and as graphic novels in trade paperback format.

The comics will be scripted by DANIEL ABRAHAM, who should need no introduction to regular readers of this blog... but I'll give him one anyway. Daniel is the author of ten books and more than thirty short stories, under his own name and the pseudonyms M.L.N. Hanover and James S.A. Corey (with Ty Franck). He has been nominated for the Hugo, the Nebula, and the World Fantasy awards, and won the International Horror Guild Award. Daniel's previous comic work includes the adaptation of my historical horror novel FEVRE DREAM for Avatar, and the original Wild Cards series THE HARD CALL for Dynamite and DBPro. When not adapating my fantasy series, he's presently writing his own, THE DAGGER AND THE COIN.

The series will be drawn by artist TOMMY PATTERSON, who won the gig over more than a dozen other artists from around the world who applied for the assignment and submitted samples. With so much top rank talent to pick from, it was a tough choice, but Daniel and I and our editors at Bantam and Dynamite were all knocked out by the character sketchs and sample pages that Tommy submitted.

Tommy's previous credits include FARSCAPE for Boom! Studios, the movie adaptation THE WARRIORS for Dynamite Entertainment, and TALES FROM WONDERLAND, THE WHITE KNIGHT, RED ROSE, and STINGERS from Zenescope Entertainment. He holds a BS in Studio Art and also works as a graphic designer.
Patterson lives in Western Kentucky with his wife and daughter.

The first issue of the monthly comic is scheduled to be published by Dynamite Entertainment in late spring 2011. The graphic novel compilations will be published by Bantam.

*** And yes, for those who were wondering, this was one of the infamous Two Big Announcements that I was originally hoping to make during my visit to Los Angeles in early January, before my holidays in the hospital knocked all my plans off the rails.

From Martin's blog:

With the year running down, we'll all soon be needing new 2011 calendars to hang on the wall. There's still time to pick up the official 2011 Ice & Fire calendar, with its gorgeous castle landscapes by Ted Nasmith.  

If you can't find the Nasmith calendar at that kiosk that appears every Christmas at your local mall, check your local bookstore.

A few copies may also be available through some of the associated sellers on Amazon, though Amazon itself seems to have sold out.

Meanwhile -- not to get too far ahead of ourselves -- but work continues apace on next year's Ice & Fire calendar as well. The artwork on the 2012 calendar will be provided by Hugo-award winning artist and fan favorite John Picacio, and he's doing some amazing stuff. So I thought I'd whet your appetites by showing you the mockup of the cover that Bantam featured in its latest catalog. 

The Picacio calendar will be released next July. This may not actually be the final cover, but it should give you a good taste of the spectacular work that John is doing. He tells me he's determined to make this calendar the best work he's ever done.

So... who would you guys like to see do the art for future calendars? Our plan is to feature a different world-class artist every year.
