If there's one thing Game of Thrones has done consistently well across its past seasons, it's these kind of set-piece, action-driven episodes, many of which, such as last season's Battle of the Bastards, or season two's Blackwater, have felt like mini-movies in their own right.
With longer episode lengths promised in the forthcoming new series, which will be told across seven instalments rather than the customary 10, we can expect its action, including the battle promised in the trailer, to be more gloriously cinematic than ever.
2. And possibly some intense Lannister brother drama
Tyrion (Peter Dinklage) is now firmly allied with Daenerys (Emilia Clarke) - and would probably like nothing more than to see his sister Cersei meet a nasty end.
But how does The Imp feel about Jaime, with whom he has always had a much closer relationship? And what about Bronn, Tyrion's old sellsword pal, who in the show has now formed something of a double act with Jaime? Will Tyrion be entirely comfortable seeing the pair face off against the deadly dragons?
3. Not to mention some intense Jaime-Cersei drama
Fans of both the show and George RR Martin's book series have long speculated that Jaime might one day kill Cersei himself, despite his love for her. Indeed, in Martin's books, part of the Maggy the Frog Prophecy arguably hints this might one day happen, although there are other theories too.
While we're not at all convinced Cersei's death will take place in the next season, it'll be fascinating to see how the pair's already complicated relationship (twins and incestuous lovers, only one of whom could be on a path to redemption) will develop.
Trailer shots of Cersei lurking in darkness, looking decidedly unhappy, also suggest that her downfall isn't too far off, and that she'll find power difficult to handle. She might have triumphed over her enemies at the end of the last season, but her machinations also led to the suicide of her son Tommen, her last surviving child.
4. Euron Greyjoy could be one of the best villains yet
In a recent interview with Empire magazine, Euron actor Pilou Asbæk promised fans of the show that, when it comes to the weekly sadism-and-murder quota, not even the show's most bloodthirsty fans will be mourning the loss of Ramsay Bolton.
"The psychos I've encountered have so many different sides to them. So each scene I've done with Euron, I pick a new thing I wanna show. 'This scene I want to be charming.' 'This scene I wanna be a molester.' 'This scene I wanna kill someone,'" he said. "After this season, Ramsay's gonna look like a little kid."
All in all, we're fairly relieved by this. While it feels logical that human wars will eventually pale into insignificant in the face of the show's ultimate Big Bad, the Night King and his undead army, we're glad that the Thrones showrunners are still planning to include some no frills, down to earth good old fashioned human nastiness in their penultimate season.
Game of Thrones just wouldn't be the same without it.
5. We should finally get to see a Stark reunion
It looks as if Bran Stark (Isaac Hempstead Wright), who is seen in the latest trailer at the Wall with Meera Reed (Ellie Kendrick), and then in a wheelchair in the Winterfell courtyard, will finally make his way home in the next season.
This means that, at long last, he'll presumably reunite with his sister Sansa (Sophie Turner) and his half-brother (technically now his cousin, following last season's reveal) Jon (Kit Harington).
But many are also hoping that Arya (Maisie Willians) is heading North too. A previously released image from season seven, shown below, appears to show the character at Winterfell; it's admittedly tricky to tell, given the limited background on show, but it certainly looks a bit like the ancestral Stark stronghold.
In the latest trailer, too, it looks as if Arya is dressed for cool weather, again suggesting that she is heading home.
After seeing the family scattered for so long, with many members unsure just who was left alive, seeing the surviving Starks united in seasons seven should be am immensely satisfying, not to mention moving experience for longterm viewers.
6. There might finally (maybe, possibly) be a Cleganebowl
Then again, there might not. But we can but hope.
A Cleganebowl, for those not in the know, is a term used by fans to describe a long-anticipated final showdown between The Hound (aka Sandor Clegane) and his brother The Mountain (Gregor Clegane), who is currently acting, albeit in undead form, as Cersei's personal bodyguard. (Most of the fans hoping for a Cleganebowl also hope that, should such an event take place, The Hound will be the victor.)
While there's no real evidence that the longed-for Battle of the Brothers will ever take place, those of us who cling to this theory were heartened by a shot of Sandor (Rory McCann) in the recent trailer, in which he appeared to be standing in the King's Landing Dragonpit, brandishing a sword at an unseen assailant. Could this be a sign?
7. The Sansa-Littlefinger dynamic should get interesting
Last year, we saw Sansa feed her husband Ramsay to his own dogs, and walk away with a smile on her lips as he was torn apart.
It was a thrilling moment - and one that showed viewers just how far the character, who began the show as a romantic, naive dreamer, has changed since the earliest episodes.
That said, the latest trailer hints that she'll face a much more complex conflict when it comes to her relationship with the manipulative Petyr Baelish (Aidan Gillen), aka Littlefinger, whose voice can be heard in the teaser's opening scenes.
At the end of season six, the arch-schemer revealed his ultimate desire to Sansa, telling her: "Every time I'm faced with a decision, I close my eyes and see the same picture. Whenever I consider a question, I ask myself, 'Will this action make this picture a reality?', pull it out of my mind and into this world."
"And I only act if the answer is yes," he continued. "A picture of me on the Iron Throne, and you by my side."
But while Littlefinger has managed to control Sansa, and many others, in the past, we're not how long he'll be able to maintain any kind of hold over the eldest Stark daughter in the future, or whether he'll ever be able to successfully turn her against Jon.
Furthermore, Sansa doesn't yet know the full extent of Littlefinger's crimes, or the part he played in her own father's downfall.
Once upon a time, she might have been pliable, but her experiences at the hands of Ramsay Bolton will have left her a more hardened, ruthless person.
Baelish is no fool, but will his love for Sansa (a deeply creepy love, that's really more of a transference of his long-held passion for her mother) lead him to underestimate just how dangerous she can be?
