Because Sony doesn't pay Activision to get DLC sooner, and as such, will still be in the back seat. This is absolutely nothing new, and it makes it so the patch cannot be applied right now, as the patch adds the M1 Irons into the game.

And since this is a last-gen console on the topic, DLC and updates will be naturally delayed due to it not being directly from Sledgehammer Games.
