The first cinematic trailer, in which Geralt dispatches three Nilfgaardian soldiers who have paid him the bounty for a young Leshen and are about to lynch a woman for simply trying to stay alive in No Man's Land. With just a stolen knife, an Aard, and his two hands, the White Wolf makes mince-meat of them, leaving the leader teetering on a barrel with a noose around his neck.
Vesemir: Don't meddle. Take the reward and let's go...
Woman: Help me!
Black One: Knew you Witchers wouldn't scorn Imperial gold. Tough hunt?
As cool as that sounds, the truth is actually the opposite. Wild Hunt restores the option for the player to choose neutrality in the politics of the world, which wasn't an option in the previous game. Based on the information released so far, the player can choose to meddle in favour of the Northern Kingdoms, Nilfgaard or neither.
The Sword of Destiny Trailer. Charles Dance as Emperor Emhyr Var Emreis, Yennefer, Ciri, Vesamir, Eskel and Lambert, maybe even Letho; finally return or make their appearance for the first time in the video game's canon.
Geralt's tracking abilities get to show their true worth as he recreates what happened on a battlefield between Temeria and Nilfgaard.
The Black One who takes off a sprinting horse's head with a single swipe.
All of Yennefer's displays of magic, including the combination of ice, lightning and earth Circles of the Elements to divert an entire Nilfgaardian heavy cavalry line around her and bury them alive, plus the metaphor of leaving behind her frozen heart in the form of the crow's skull.
