Well GTA 6 will come on disc for Playstation 5 too. But it will be just a code in a box, confirmed by Rockstar. And honestly don't think the XBOX version will be different. I think that wasn't the best example.^^ I do actually expect Microsoft stop producing discs for newer games, but we need to wait and see. If you really want a disc, I think there is not really good choices in the future.

Sorry for being this negative, but that is what I believe.
