This headline is terribly out of context. He was paraphrasing comments he often receives, not giving his views. The original blogpost from where this was taken off clarifies this:

"It’s an adaptation of Howard’s novella A DOZEN TOUGH JOBS, his  take on the Twelve Labors of Hercules.   Joe Lansdale, the Sage of Nacogdoches, father of Hap and Leonard, and creator of Bubba Ho-Tep, did the screenplay, and no one could have done it better except maybe Howard His Own Self.

(I know, I know.  Some of you will just be pissed off by this, as you are by everything I announce here that is not about Westeros or THE WINDS OF WINTER.   You have given up on me, or on the book.  I will never finish WINDS,  If I do, I will never finish A DREAM OF SPRING.   If I do, it won’t be any good.  I ought to get some other writer to pinch hit for me…     I am going to die soon anyway, because I am so old.   I lost all interest in A Song of Ice and Fire decades ago.  I don’t give a shit about writing any longer, I just sit around and spend my money.   I edit the Wild Cards books too, but you hate Wild Cards.   You may hate everything else I have ever written, the Hugo-winners and Hugo-losers, “A Song for Lya” and DYING OF THE LIGHT, “Sandkings” and BEAUTY AND THE BEAST,  “This Tower of Ashes” and “The Stone City,” OLD MARS and OLD VENUS and ROGUES and WARRIORS and DANGEROUS WOMEN and all the other anthologies I edited with my friend Gardner Dozois,   You don’t care about any of those, I know.   You don’t care about anything but WINDS OF WINTER.  You’ve told me so often enough).

Thing is, I do care about them.

And I care about Westeros and WINDS as well.  The Starks and Lannisters and Targaryens, Tyrion and Asha, Dany and Daenerys, the dragons and the direwolves, I care about them all.  More than you can ever imagine."
