The Witcher 4 teaser fuels theories that Ciri may replace Geralt

The first teaser image for The Witcher 4 suggests that its main character could be Ciri, the adopted daughter of series protagonist Geralt. 

As developer CD Projekt Red noted in a brief announcement confirming that The Witcher 4 is officially in development, the reveal image features a Witcher medallion and promises "a new saga" for the franchise. It's clear that big changes are coming to the Witcher games, and that medallion could be a big clue. 

It's partially buried in snow, but the featured medallion seems to belong to the School of the Cat, which oversees a separate Witcher faction than the School of the Wolf that Geralt follows. Ciri initially trained under Geralt at Kaer Morhen, the base of the School of the Wolf, but she did come to possess a medallion of the Cat after seizing it from Leo Bonhart, who was said to have killed at least three Witchers. 

This isn't just coming from the Witcher books, either. Ciri is shown sporting a medallion of the Cat in The Witcher 3, so if this teaser image is as literal as it seems, The Witcher 4, or whatever its final title ends up being, could well be a new story starring Ciri that picks up after the events of The Witcher 3 and its canon ending. 

We're veering even further into speculation here, but on top of hitting some popular story beats, casting Ciri as the playable character of the next Witcher game could also allow CD Projekt Red to go wild with gameplay. Ciri possesses Elder blood, after all, and has access to rare and powerful magics which would probably be pretty fun to wield in combat and use in exploration. 

It's still unclear what's in store for The Witcher 4, including its official title and release date, but we can safely assume that its "new saga" will take the
