Game of Thrones co-creator D.B. Weiss revealed in a new interview with Vanity Fair that they plan on ending the popular HBO series after seven or eight seasons. That's just one tidbit of new information in the interview, which also includes quotes from author George R.R. Martin, the other co-creator David Benioff and series star Peter Dinklage (Tyrion Lannister). The actor is also featured on the magazine's new cover, alongside Emilia Clarke (Daenerys Targaryen), Lena Headey (Cersei Lannister), Kit Harington (Jon Snow) and Nikolaj Coster-Waldau (Jamie Lannister). Check out the cover, along with another photo featuring Emilia Clarke, Iain Glen (Jorah Mormont) and their dragons, and a behind-the-scenes video of the Vanity Fair cover shoot, before reading on for more details about Season 4.

As many fans know, the show is based on George R.R. Martin's A Song of Fire and Ice novels, with the author still working on sixth and seventh installments. D.B. Weiss revealed that they plan on giving the show a proper ending that falls in line with what happens in the books.

"It doesn't just keep on going because it can. I think the desire to milk more out of it is what would eventually kill it, if we gave in to that."

Since the ending isn't exactly set in stone yet, in regards to the novels, David Benioff revealed that he and D.B. Weiss went to visit George R.R. Martin for a week, to find out how it all ends, in case the show does end up catching up to the novels that have already been written.

"Last year we went out to Santa Fe for a week to sit down with him [Martin] and just talk through where things are going, because we don't know if we are going to catch up and where exactly that would be. If you know the ending, then you can lay the groundwork for it. And so we want to know how everything ends. We want to be able to set things up. So we just sat down with him and literally went through every character."

George R.R. Martin also talked about that meeting, while remaining hopeful that the show will not catch up to his writing.

"They are (catching up). Yes. It's alarming. I can give them the broad strokes of what I intend to write, but the details aren't there yet. I'm hopeful that I can not let them catch up with me."

The author added that the young actors on the set, such as Maisie Williams (Arya Stark), are growing at a faster rate than their characters in the books.

"This is a serious concern. Maisie was the same age as Arya when it started, but now Maisie is a young woman and Arya is still 11. Time is passing very slowly in the books and very fast in real life."

Peter Dinklage, who won an Emmy Award in 2011 for his portrayal of "halfman" Tyrion Lannister, talked about how he refuses to call Game of Thrones a "fantasy" show, and how he embraced it because of how it subverted the dwarf stereotype.

"It just seemed like something I had never come across before, especially in the fantasy genre, which I still refuse to call this, even though we have dragons. It is just something that I was so eager to embrace, because it turned the dwarf stereotype in the fantasy genre on its head. And he's a hero at the same time. Even in The Lord of the Rings, which I really loved - I loved those books as a child and I adore Peter Jackson's movies - but there's just that thing with the dwarf stuff. That's complete fantasy. I had done The Chronicles of Narnia, with the long beard and all of that, because I definitely wanted to explore that and have an opinion of it from the inside, but I just feel like this character, Tyrion, was a complete human being. Shock!"

Creators D.B. Weiss and David Benioff also confirmed in a joint email statement that President Barack Obama receives early epiosodes.

"One perk of being the most powerful man in the world: yes, you get to see episodes early."

The highly-anticipated Season 4 of Game of Thrones debuts Sunday, April 6 at 9 PM ET on HBO with "Two Swords".
