*Game Director is fan of Naughty Dog's games & later also mentions God of War & Hades II & Indiana Jones Game & that he's waiting for Kingdom Come Deliverance 2
*400 people work on Witcher 4, all of them are fans of Witcher
*They collaborate with Epic Games
*Trailer was meant to feel like Sapkowski's short stories
*New regions of the map, that we haven't experienced before
*He likes how people analyze trailers by frame to find hidden details, and they read our comments
*People who are in the trailer will actually be in the game. And you will be able to fight that monster in W4.
*They still treat books as Canon, but also what they've did in the games
*Geralt is still living in Corvo Bianco, killing monsters from time to time, and he's playing Gwent.
*They make decisions on how game will look like based on story's narrative, and not on "what would give us cool gameplay", meaning if they decide story is going somewhere - they focus on making that cool after, not the other way around.
This is in context of Ciri, so it probably means: "We decided to go with Ciri as Witcher, because it makes the most sense for the story, not because it would be cool to play as a woman".
*They still build worlds and decisions as other shades of grey, and not black & white.
*About Ciri being "fat" - You haven't seen her in few years, she's older, trailer gives different light and it makes face different despite the same topology.
*About "Why a Woman" - Direct translation: "I feel like just responding - because yes". Ciri was a main character of Sapkowski. And in Witcher 3 it's foreshadowed with Ciri becoming playable character. And they find heavy potential with Ciri's story.
*They try to not pay attention to these "culture wars" (my word, they don't call it directly, but it's basically what they mean), and are instead focused on making good game with real story without trying to lie to the player.
