Sony has bought exactly 1 existing game of note, Destiny, and neither it or Bungies next game going to be Playstation exclusives.
Microsoft has bought all of Zennimax and will be taking all future games off Playstation.
So I don’t know what you’re basing your points on.
Destiny is the only game Sony has bought of note ever, and it’s not going exclusive, nor is Bungies next game. Sony buys talent, not game libraries.
