Crypts of Winterfell & Release Date

Game of Thrones fans rejoice! We have an official release date: April 14. Before Sunday fans only knew that the final season would begin in April, but what day in April wasn’t known.
Then the HBO Twitter account sent out a tweet of a screenshot from the “boss’ that said the date would be revealed before the premiere of True Detective.
Well, the “boss” kept his word and before season three of True Detective began it was revealed that we begin our trip back to Westeros on April 14 at 9 p.m.
I will not be doing ANYTHING else that day. I may even plan a viewing party at my place.

Next: can we talk about this trailer? Jon, Arya and Sansa in the Winterfell crypts, and they see statues of themselves as the crypt starts to freeze… WHAT IS HAPPENING? And where did the feather come from? Is it Bran, aka the Three-Eyed Raven? You don’t see his statue in the crypt… he’d be the only other Stark left, and the true male heir to Winterfell. I have to tell you the suspense is killing me, but at least we have an official date. Let the countdown begin!
