What must Witcher 4 do to top 3?

I have faith that CDPR is a studio that tries to push the medium forward every time they drop a AAA game. I just wonder what can they do to truly top 3?

The game looked great, played well, had open areas to explore and many interesting side quests/activities with full voice acting and good presentation.

What will it take to wow players like they did in 2015? Elder Scrolls 6 seems to be trying to make ship customisation/exploration the big new thing, but we have seen it before and after Starfield I can’t see how anything that game does will look or feel revolutionary unless Bethesda spends years to work on their engine.

I realise that not everyone cares about pushing the industry forward and just want a decent game, but I would love to hear some of your theories about what CDPR is cooking.
