Pretty sure Spencer said during and after the several acquisitions that they have no interest in making existing games that exist on multi-platforms away from the other platforms. So i think Doom, Fallout, more than likely elder scrolls as well (though we'll see about that depending on the rumored Starfield ps5 version) would still make it to PS5. If their new IP catalog makes its way to PS5, then yeah.
That being said, if its on gamepass day 1, why wouldn't people think of that as a major perk over spending 70 bucks (100 if your Canadian like me) on every title.
