RussianUkrainian blogger and marketing man Sergey Galyonkin - who tipped off the closure of the STALKER 2 project earlier this year - has claimed that Bethesda now have the rights to make a publish a STALKER game. They apparently do not have rights to the extended universe. GSC owner Sergei Grigorovich has not sold the brand, but apparently Bethesda could now make a game based on the property with their own technology. We'll report more on this as we get it.
We've contacted Bethesda for a statement. UPDATE: Currently they are saying "No comment."
