(Spoilers Extended) Are we headed for another Game of Thrones situation with Dunk and Egg?

So the showrunner for A Knight of the Seven Kingdoms has confirmed that GRRM has shared broad future plans;

“He has shared with me about 10 to 12 more little outlines for books, for novellas, taking Dunk and Egg all the way through their life,” Parker tells The National.

And the production model mirrors the situation with GoT

“Right now, we’re focused on one, and we’ll see how the world responds to that. We’re making two at the moment,” Parker says. “Hopefully, everybody likes it and we get to keep doing these. Certainly, I love doing it. I love writing in this world, and it’s a wonderful story. So, I hope we get to make as many of these as possible.”

A pretty familiar setup. GRRM supplying outlines, endgame beats, and historical landmarks, while the showrunners fill in connective tissue if there is enough demand for more seasons. Since we aren't getting a flurry of D&E novels anytime soon, HBO’s adaptation is very likely the only chance we will get of seeing events like Summerhall.

And if we get that far, You can also probably expect increasing compression as it goes on. Early seasons may map cleanly onto individual novellas, but once the show outruns the existing material, multiple unwritten stories will likely be collapsed into single seasons.
