Apparently the blessing is coming from Sony itself that wants to hurt Steam monopoly. The biggest videogames giants are uniting against Steam, and in this case, SONY is cooperating with Epic Store.
The rumor looks like very real in light of the recent news that Sony exclusives such as Heavy Rain and Detroit: Become Human are coming to PC as Epic Store exclusives.
The source is the Russian game journalist Anton Loguinov. He has a bad reputation of being a sellout. He's famous for his meme of giving every game 10 out of 10. But he also has access to insider information due to his good relations with big companies. In his video he confirms that not only Quantic Dream games are coming to PC, but also Death Stranding.
