With events on "Game of Thrones" rushing along, as HBO programming head Michael Lombardo hinted of two more seasons of the popular series, George R. R. Martin is under more pressure to announce the "Winds of Winter" release date sooner than later.

Michael Lombardo talked to reporters during the Television Critics Association's summer press tour where he said that the "Game of Thrones" could run for two more seasons, at least.

"The question is how much beyond seven are we going to do," he said, adding that David Benioff and Dan Weiss felt "like there's two more years after six. I would always love for them to change their minds. That's what we're looking at right now."

"Game of Thrones" season 6 will premire in April 2016 and George R. R. Martin had said that he aims to announce the "Winds of Winter" release date before then. If there's going to be a season 7 and season 8, the HBO series would air also in the spring of 2017 and 2018.

"Which brings us to Martin's 'The Winds of Winter' and 'A Dream of Spring,' Many 'ASOIAF' fans have abandoned hope about the author finishing the beloved series by the time the HBO show ends," according to IB Times.

"If that happened, the fate of Westeros would be revealed before Martin had a chance to finish the tale he started."

George R. R. Martin wrote on his blog that the "Game of Thrones" and the "A Song of Fire and Ice" series might be parallel, but they could also run in different directions without necessarily harming the overall concept.

Nevertheless, "The Game of Thrones" is running out of source material with the delay in the "Winds of Winter" release date.

"It was pretty much guaranteed Martin would not be able to finish the last two novels before "Game of Thrones" went off the air. If there's another season, we could see "A Dream of Spring" along with "Game of Thrones" Season 8," the article said.
