Chinny-reckon! Only superhero movies and Star Wars announce sequels years in advance. Everyone else pretends nope, there's just this one thing we're doing right now and you'll have to wait to find out if there'll ever be another. And so it is that CD Projekt Red are protesting that they have no current plans for a fourth Witcher game, claiming that the upcoming Blood & Wine expansion for The Witcher 3 "is the end."
Following Blood and Wine, they've got the long-anticipated sci-fi RPG Cyberpunk 2077, which has presumably benefited from a huge cash-pump in the wake of Witcher 3's huge success.
Speaking to Bertie on Eurogamer, CDP co-founder Marcin Iwinski claimed that "We don't have anything planned as of now to be honest on the next Witcher... Never say never [but] right now it's really Blood and Wine. This is the end. Blood and Wine is [the] closing and there won't be any Witcher any time soon - if there ever will be one. And I would really like to see how people feel about it, if they will enjoy it."
He did, however, also note that "We are a publicly traded company so we cannot comment on that" - i.e. when you've got shareholders you can't easily speak for them, or spook them by disrupting far-off marketing plans.
There is a "triple-A roleplaying game" due from CDP following Cyberpunk, with 2017-2021 noted as its theoretical launch window, which could or could not be another Witcher. And could or could not be a Witcher starring Geralt even if it is one, given how strongly CDP are hinting that Blood & Wine is the end of his story. "Blood and Wine is the dot on the end of a beautiful sentence which is The Witcher 3."
Man, I so need to finish the main game. Though perhaps I've got until 2021 to do it.
