Ofcourse they will. They are current gen games getting boosted graphics on much more powerful hardware. But they are still current gen gamed built for current gen hardware. That isn't proof cross gen doesn't hinder next gen development.Both are current gen games that will look amazing. Witcher 3 is getting a next gen update. I doubt that they rewrite the game from scratch.
My whole point is that people used the Halo debacle as ammo in their fun little war.
It is the same as Miles Morales on PS5. It just looks like a prettier version of the PS4 game.
