Psygnosis was wholly owned by Sony when they made Wipeout for the Sega Saturn. SOE also owned by SCE makes PC games which are non Sony platforms.
Not saying it is happening with this title but being owned by Sony doesn't necessarily mean the game is exclusive to Sony platforms.
In this day and age that's really doubtful. Why would someone owned by Sony even release a potential system seller IP on a platform that they don't own? Lol.
