It will lead to one of two things. It won't happen overnight, but one of these WILL have to happen eventually. Either Sony will have to improve PS now to he as good as gamepass (long way to go, but it can be done), or watch as MS continues to draw more and more consumer support as the digital age continues to develop. The value of gamepass is just too strong for people to prefer paying 70 bucks for each individual game.
uuuuuh, PS5 has more backwards compatible games (4000+) Vs at most Xbox's 3197, and while Microsoft is investing MORE in GamePass, you can't pretend Sony doesn't also have something similar with PSNow (and with the PS+ Collection being a part of PS+). They're not the same, as we've established, but they're similar enough that you can't really pretend Sony isn't trying or that Microsoft is pulling way ahead or something.
