Going PC hurts Sony more than it does Microsoft though.
Microsoft = third in sales, has a seeming plan to focus gaming everywhere and to grow Xcloud and streaming that may forestall needing to produce a console someday.
Sony = second in sales, their bread and butter is SIE ever since their ability to make decent technology outside of PlayStation fell off.
Sony needs their console to be successful more than Microsoft does. In the '90s, Sony was all good because they were selling Walkmans and Discmans and TVs for profit along with PlayStation. They had the cash to buy an American movie studio for well over value only a few years after they bought CBS Records. Now we're asking if that Bungie purchase was too much money for them.
