Based on George R.R. Martin's novels, there's a lot of Game of Thrones left to tell.

And HBO Co-President Richard Plepler wants to assure viewers: the network won't abandon the series without resolving every conflict.

“We told [author George R.R. Martin] we’d go as long as he keeps writing,” Plepler told journalists at last night's Television Critics Association’s press conference, while Programming President Michael Lombardo added:

“I promise you we won’t stop it before it’s ready to stop... There’s a great relationship fans have with the show and we appreciate that. We’ve never seen people get so excited about casting [decisions].”

The most recent casting decision involves the choice of Liam Cunningham as Davos Seaworth.

Elsewhere, Lombardo did have bad news for viewers: there are no plans to expand seasons beyond 10 episodes "without diluting the quality of the execution.” Each installment just takes too long and costs too much money to produce.
