It just hit me:

Cyberpunk 2077 is meant to be our world in the (dystopean) future. Therefore, the retrogame-fans in Cyberpunk would probably still know (and love) a 60-year-old game called Witcher 3 - Wild Hunt.

Ciri mentions in Witcher 3, she has visited a where "people had metal in their heads, they used megascope like devices to wage war from a distance and everyone had a personal flying ship"
This hints at a sidestory in Cyberpunk featuring Ciri!

So, if Ciri actually is in Cyberpunk 2077, this would create the ultimate paradoxon - a character from a (then) "retro videogame" who is visiting the real world, and even mentions this visit 60 years earlier in the retro game!

crazy stuff :-D

It's true Ciri mentioned a cyberpunk-esque world, but CDPR said several times that we won't bump into Ciri in Cyberpunk 2077. Would definitely be fun to see some kind of easter egg for her.

This is from 2 years ago, so it's possible that Badowski changed his mind.
