Game of Thrones fans could enjoy another three seasons of the HBO fantasy-drama hit, but it's going to be without Jon Snow. Speaking Thursday at the Television Critics Association summer press tour, HBO programming president Michael Lombardo said he was "open" to extending the length of the show and dismissed claims that it would end with seven seasons. Lombardo added executive producers David Benioff and D.B. Weiss are "feeling probably like two more years after [Season] 6." But the HBO executive also quashed speculation that Jon Snow might still be alive. "Dead is dead. He is dead," Lombardo said. "Yes everything I've seen, heard and read, Jon Snow is indeed dead."
