There's no snowball's chance in hell I'll ever buy a console game without a disc. At that point, I'll make my purchases from Steam or none at all. If they want to move this way, I'll guarantee you the PS5 is the last dedicated gaming console I'll ever buy. Even Nintendo, the lazy, greedy sub-par rehash machine know as the Switch has been utterly dry and disappointing for me. It's my indie games machine, mostly. So I probably won't be in the market for their next hunk of plastic either.
I predicted it would be the larger publisher pushing to abandon physical media first. Fug em, I don't need the games.
