The Witcher 4 is preparing a slightly longer advertising campaign than Cyberpunk 2077

One of the specific lessons that CD Projekt learned from the release of Cyberpunk 2077 was to be “smarter in how we want to announce and launch marketing campaigns,” said head of Polish developers Michal Nowakowski.

Although this campaign lasted about six months, given that it was just an expansion, Nowakowski added that "for a new game we would still expect a little longer - but not two-year campaign.”
