This isn’t about the writer of the games, is about the writer of the original book series that the games act as sequels. The guy hasn’t played the games because he hates them in a way, in the sense that more people know about the world of the Witcher thanks to that “fad” (quote) than to his own prose.
Already confirmed in press release that it’s only releasing for PS5 and Xbox. No PC launch on 2025.
