User blog comment:Star Metal Knight/Last EP of Season 5 warning! might be true spoilers!/@comment-26973802-20150613004749

I hope this episode reveals whether Gregor survives or not, I don't want to wait another year to find out!

Although Season 6 will be interesting. Book 6 isn't out yet so Season 6 will have to tell its own story. It seems the creators of Game of Thrones know that the fans won't want to wait for Book 6 to come out (whenever that might be, and assuming George R. Martin lives that long) and don't want to do anything to annoy us. (I'd say killing off Joffrey is further evidence of that but that already happened in the books)
