After it was leaked 2 days back, HBO has finally released the new season 6 promo on Game of Thrones’ official YouTube channel. However, there’s a slight difference between the two. At 0:14, we see Theon and looks like he is captured by Bolton guards. However in the leaked promo, at 0:14 we have Brienne charging on her horse [see above pic] as she tries to kill a group of soldiers and is being watched by someone (Theon or Podrick most likely).
Not sure why HBO decided to cut that but they added the above shot of Night’s King at 0:21 which was not present in the leaked promo [instead it shows the earlier revealed shot of two ladies kissing from the original trailer].
Here is the official promo:
And here is the leaked version:
