I hope so, they need to improve from TW3 (in particular on loot and progression system IMHO).I'm sure that at least fan feedback from The Witcher 3 and it's expansions will definitely affect certain aspects of Cyberpunk 2077 (they even mentioned melee combat as one of them), just like feedback from The Witcher 2 greatly affected Witcher 3, then Witcher 3 feedback affected the expansions and Thronebreaker.
In case of The Witcher 3 they also included some changes during game development due to fans suggestions, like expansion of the Novigrad area, changing White Bridge town into Oxenfurt, changing in-game main currency from orens to crowns, improvements to Geralt's animations for combat and exploration, as well as making Skellige less snowy (admittedly, that was one of the changes I didn't like).
I didn't know they changed that much. Very interesting! But how fans knew all those things? No trailer showed novigrad's area or white bridge... mmm...
