He also revealed, during an appearance at the South by Southwest festival in Austin, Texas, that Ed Sheeran is set to make a cameo in the upcoming season. 

The final season likely will air in 2018 and after that, Benioff acknowledged HBO might continue with a spinoff without himself and Weiss at the helm.

'I think HBO might well do [another series] and I look forward to watching it and I think it be great but I think they should get new blood in,' he said.
