The short clip uses the classic song 'Sit Down' by James and it features Daenerys, Cersei Lannister , Jon Snow, and a White Walker.
Game Of Thrones returns Stateside on HBO in June and will then be aired over here on Sky in July.
Speaking about the new season, Kit Harington said: "They spent an increasing amount of money on less episodes, so it’s gonna be much bigger in scale, the CGI … we’re trying new things, experimenting with new camera techniques. I think we’re trying to break boundaries and push past boundaries in these final two seasons.”
Here's the new teaser trailer:

Earlier this month, we wrote how the man of the moment, Ed Sheeran is to make a surprise cameo appearance in Season Seven of 'Game of Thrones'.
The show's producer revealed that they desperately wanted to get Ed on the show because cast member Maisie Williams is such a huge fan of his music.
“For years, we tried to get Ed Sheeran on the show to surprise Maisie (Williams)... And this year we finally did it," the show's producer David Benioff confirmed while speaking on a SXSW film panel.
Ed Sheeran took to Twitter earlier in March to say, "Guess the cat's out of the bag," to confirm that he will appear in the seventh series of the HBO fantasy drama, which returns to TV screens in July.
But Sheeran won't be the first musician to make a cameo in 'Game of Thrones' - already our very own Gary Lightbody of Snow Patrol, Will Champion of Coldplay, Mastodon, Of Monsters and Men, and Sigur Ros have all appeared on the show.
