The one Game of Thrones mystery we don't want to think about is when the show might call it quits.
The show's producer Frank Doelger was asked this week how much longer the series will last, according to Radio Times.
"[The number of seasons] is being discussed as we speak," Frank admits.
"The third season was the first half of book three," he continues. "Season 4 will be the second part of book three."
It sounds like the length of the show might depend on how many books get written in the series.
"George RR Martin has written books four and five; six and seven are pending," Frank says.
"I would hope that, if we all survive, and if the audience stays with us, we’ll probably get through to seven seasons," he concludes.
Hmmm. How does this make you feel?
On the bright side, with the show only on Season 3 currently, it's clear that Season 7 is a long ways down the road. And we love the idea of having at least four additional season after this current one.
Still, we wonder why the show has to end at Season 7. Would HBO really be okay with killing off a popular series at that point?
After all, another popular HBO show, Entourage, ran eight seasons. And plenty of network shows go much longer than that, with CBS drama CSI recently having been renewed for a whopping 14th season.
For now, we'll just try to enjoy the show and pretend that winter will never come for it.
