It didn't exist a week ago. NOBODY was asking for it. Like AT ALL! Now all of a sudden it's the worse thing in the world if it doesn't get a physical release?
It's a new release AAA game, AFAIK physical PS5's were preordering in far higher numbers, there is a demand for physical games. The only reason to not release it physically is to save money. I guess all those new players with physical PS5's can still download the digital version!
