The final expansion for The Witcher 3 will send Geralt to a new open area, Letten, connected to one of his oldest friends. However, Polish voice actor Jacek Kopczyński, who voiced Dandelion, stated that he only recorded new lines for the character for The Witcher 4.
Regarding the upcoming expansion for The Witcher 3: Wild Hunt – Songs of the Past, the actor said that he is still waiting for an invitation to the studio to read the script and record lines, as he has not yet been invited.
This seems strange, as Letten is the bard's homeland. Perhaps Dandelion will only have a small cameo, like in Blood & Wine. Meanwhile, Kopczyński's involvement in The Witcher 4 has already been confirmed by his own words.
