George R.R. Martin offered an update in his end-of-year blog post on several Game of Thrones-based TV series that are currently in the works, noting that "HBO and I have our own animated projects, set in the world of A Song of Ice & Fire. None of them have been greenlit yet, but I think we are getting close to taking the next step with a couple of them. When this last round of development started a few years back, we had four ideas for animated shows, with some great talents attached. Writers rooms and summits, outline and scripts followed in due course... but, alas, two of the original projects were subsequently shelved."
Work on the other two animated projects, however, "continues apace," Martin wrote, adding that "meanwhile, we have moved Nine Voyages, our series about the legendary voyages of the Sea Snake, over from live action to animation. A move I support fully. Budgetary constraints would likely have made a live action version prohibitively expensive, what with half the show taking place at sea, and the necessity of creating a different port every week, from Driftmark to Lys to the Basilisk Isles to Volantis to Qarth to... well, on and on and on. There's a whole world out there. And we have a lot better chance of showing it all with animation. So we now have three animated projects underway.... Will any of them make it to air? Happen? No way to know. Nothing is certain in Hollywood."
