George R.R. Martin probably gave away a massive plot spoiler about the next book in the A Song of Ice and Fire series, The Winds of Winter, and the Game of Thrones TV show, during an interview with io9.
We warned you, right? You saw that warning? Just in case:
You introduce characters, and sometimes they take on a life of their own.
Some major characters — yes, I always had plans, what Tyrion's arc was gonna be through this, what Arya's arc was gonna be through this, what Jon Snow's arc is gonna be. I knew what the principal deaths were gonna be, and when they were coming. That would be the closest thing.
That's it. Did you see it? Jon Snow. The present tense. IS. Which means that he is still alive. Jon Snow is aliiiiiiiiive! He may have been stabbed over and over by Bowen Marsh and other black brothers... but assuming that George R.R. Martin didn't throw in a present tense to mess with us, there's still more to come from the Bastard of Winterfell. And we can't wait to see what happens next.
