I don't know about 'winning' (I've always disliked franchise wars tbh) but with MS releasing all their exclusives on PC as well and having cross platform saves as well (My old XB1 Forza Horizon 4 save can be loaded on the PC version if I load it through the PC games pass) is a massive advantage.
Sony being pigheaded in this regard especially considering their exclusivity police, meaning there's a load of games I may never get to play unless I buy a Playstation. has irked a lot of people.
I do wonder if it's a cultural thing though. Japanese companies in the games industry are fiercely protective of their way of doing things, even the ridiculous practice of releasing games in Japan before the rest of the world in this day and age.
Time will tell I suppose.
