Nah, even with being a PC gamer, I'd still keep a PS5 as I still prefer to play my games using the PS controller if its a series I grew up with on that platform. As, its not saying Tekken on PC is bad, is saying I know the combos on PS, thus will always get the series on PS, no different then I'd still get the Company Of Heros series on PC if they make some 3rd game and have it on all platforms or something.
So God Of War being on PC, doesn't mean thats the way I want to play it even with owning a PC, would be like asking if I'd play all my games on a fucking phone or something JUST cause its coming out on a phone too or something odd like that. Doesn't mean its my preferred way of gaming on some IP.
