According to a Polish newspaper, it seems like CD Projekt is preparing to fight off a hostile takeover from an unknown company. They will have an extra meeting with shareholders in the end of the month and is seeking to buy back their own stock for 250 million PLN ($64 million), in an effort to fend off potential suitors.
We can only speculate which companies that would be interested, but one candidate is of course Vivendi who has been trying to buy Ubisoft and wants to get back into video games, but there's also the usual suspects like Activision and EA. While it may seem a bit far fetched to think that free-to-play focused Asian giants would make a move, you can never rule out Tencent in this sort of situation.
CD Projekt are of course best known for their studio CD Projekt Red and The Witcher series, but they also own popular DRM-free shop GOG.com.
