HBO dropped the first look at Game of Thrones Season 6. Is Jon Snow dead or alive?
"They have no idea what is going to happen."
That is how the trailer ends and it is accurate. All we see in it is people dying, which is no surprise in this series. George R.R. Martin, the author of the A Song of Ice and Fire series on which the show is based, has not released the next book in the series.
Feel free to wildly speculate now until April when the show returns.
