David Benioff states
here that the adaption of
A Song of Ice and Fire is the project he is pushing forwards next. Whilst HBO were considering it, he was working on the
Wolverine movie. With that in pre-production, it sounds like he is now keen to crack on with the ASoIaF TV series. Exactly what that means - if he's simply going to be on the phone to HBO saying, "What gives?" or even actively shopping it around to other studios for when HBO's option expires later this year - remains to be seen.
