Day 1 DLC is a consequence of spinning shiny discs is it not? They have to finalize a version to send to disc manufacturing months in advance of actual release date just like any typical physical goods manufacturing/distribution. There's clearly lots of work that can and is done on the code during that shiny disc making period. So it stands to reason that what ever the code is on the shiny disc once released is so antiquated it is not even worth the plastic is stamped in.

Do digital release only games suffer from Day 1 DLC like this? I'm not a gamer, so I have no experience with this.
