The same thing will happened to Sony
Its not instantanious but a rather long process
Sony studio already having trouble releasing game they took 4-5 years to make games now rhey have to consider PC in mind
For PC they have to spend more time to make the game work in various different settings cos theres standard requirement for pc games lile low, medium and high settings
Not to mention sony already lost so many partner like quantic dream, japan studios, ready at dawn, annapurna, liverpool studios etc
The remaining studio has to work harder now to compensate the loss of those studio and have to pump more game ( now have to consider pc in mind) > have to work harder to finish deadline > put a pressure in those studio > could lead to worse product / cut content/ cheap copy paste embironment/ rushed buggy game/ weaker rushed story etc
And then latter slowly after the brand reputation is tarnished you can put sony into that same xbox pedestal
