New Game Of Thrones Commercial Is Ominous

My life right now is pretty much just a prelude to what's coming, what's really important. I'm talking, of course, of the return of Game of Thrones on April 24. I know you are probably the same. Whenever one of these trailers come out, they get disected for clues as to what's coming. Since the show has pretty much caught up with the books, people like me who were smug in their knowledge of coming events in past seasons, are now in the same boat as everyone else. We definitely see some interesting stuff. Who is Ramsay and the Boltons going to war with? Could it be the resurrected Jon Snow and an army of Wildlings? Who is the knight with the Targaryen seal on his armor fighting? Is it a young Ned Stark in a flashback? What's going to happen to Daenerys at the Dothraki capital? Is Drogon coming to save her? What "face" is going to go into the hall of faces? Was that a giant breaking down the doors of Winterfell? And, (holy crap!), did the Night's King just grab Bran? 

None of this deserves the spoiler warning because it's all speculation on my part. What do you think?
