Yeah this fits!
Today Bandai Namco has confirmed that Geralt from The Witcher series will indeed be a guest character in Soul Calibur VI. The trailer below shows him off to great aplomb, showcasing his skills and the fact that he slots in nicely with the rest of the demonic-tinted crew.
CD Projekt Red notes that they've directly collaborated with Bandai Namco for this crossover to "faithfully recreate Geralt" with shared Witcher 3 assets. Doug Cockle, the current voice of Geralt, is reprising his role.
He'll also launch with his own Kaer Morhen arena (and song, "Hunt or be Hunted"), and evidently all platforms, PC, PS4, and Xbox One will be getting the guest character.
