I wouldn't hold my breath on that one
Cyberpunk dev would appreciate if you’d stop asking about The Witcher’s Ciri, please
From the same interview:
“Maybe you will change your mind,” said Iwiński, putting his hand on Badowski’s shoulder, before turning to me. “There is a little hope there.”
So I wouldn't completely count it out. But I doubt it's gonna be the "OMG I hope you run into Ciri!" situation the more obsessive fans are hoping for. It'll probably be a really obscure easter egg, which would be enough for me.
