Your talk about sony bringing their exclusives to PC is an "gigantic if"! Chances of Sony putting exclusives on PC ( day 1 exclusives) are low to nonexistent, but....
I have to say that i agree whit you ( partially, cause i don't see great adavantages on having switch, other than exclusives.), whit no exclusives i would drop playstation and stick to PC... same is valid for Nintendo, and i would drop Nintendo whit a great deal of satsfaction since i think their hardware and sofware are overpriced as a#@%=×
Imho, no great console exclusives = no buy, and by exclusive i mean games that can only be played on the console of choice, no bullshit "windows exclusive"...
