So what do you think of all this ? Imo it doesnt make any sense. The graphics should be superior to witcher 3. It should be more realistic, not more cartoonish or comic style
Intentional decision, maybe. And frankly speaking, a swell one. Every other game wants to be "realistic"; not ever game needs to, and cyberpunk lends itself well for a bit of a comicbooky twist.
In the passages you quoted, they are speaking of aesthetic direction, not graphics. A more humble ("realism" wise) and stylized aesthetic direction might allow them to put more stuff on the screen without it becoming an excessive resource hog. And based on the trailer, the both, the graphics and aesthetic are just fine. Even less would've sufficed.
