I think chances are it's CD Projekt. Why? They've always been really close with Xbox similar like Bethesda is. They are also big on PC and are owners of GOG a big storefront for games. They are now cheaper then they were and shareholder would be hesistant to get a good price on their stock. Also the hands-off approach from Xbox with a studio based in Poland would work well where the CEO of the company undoubtly can stay on as studio head.
Good, good. Supporting acqusition of developers which games are multiplatform and huge sellers.
