"Game of Thrones" fans excited by four or five spinoffs/prequels to the hit fantasy drama should hold their, um, dragons.

HBO programming president Casey Bloys offered new details on the potential spinoffs to Entertainment Weekly. And basically, he cautioned everyone not to expect multiple spinoffs and to be patient because the projects are in the "embryonic" stages.

"I haven't even seen outlines," he noted. "In the press at large, everybody said, 'there are four spinoffs' and they assume that means each one is happening and we're going to have a new 'Game of Thrones' show per quarter. That's not what's going on. The idea is not to do four shows."

Right now, the network is focused on airing Season 7 this summer and working with showrunners David Benioff and D.B. Weiss on preparing for the eighth and final season.

And though four (or five) ideas are in the works, only one — if any — might make it through to become a series.

"The bar is so high. If you only developed one, everything would rest on that one shot," Bloys said. "It's such a special show. I want to make sure that [any prequel] feels worthy. We have some amazing writers who want to take a shot at this. They're also looking at different times in the universe and all will have different feels. This increases our odds of finding one that's unique."
