Microsoft’s not teasing Halo on Playstation out of desperation. They’ve nearly ended consoles.
Which is kind of a good thing. The console wars have been large irrelevant for the past 20 years, because PC already won.
Really, Steam won. And if Microsoft isn’t careful, all of that planning to shift gamers towards PCs will have them land squarely into the Steam/Linux ecosystem. It really depends on how hard Microsoft wants to abuse their near-monopoly with Windows 11.
