The good news from this is the author of the Mistborn series is offering his books for CDPR to makes games out of.
So if Sapkowski was attempting to hurt CDPR in some way, he's already failed. They have yet another IP potentially lined up because of him.
It will only get better for them anyways as its public knowledge how Sapkowski feels about games and gamers so other authors see how well his books sold after CDPR made the games and want their stories as games too. CDPR did really well and im totally on their side on this whole thing.
