UPDATE: The PlayStation Store has been updated to state that the Call of Duty: Black Ops III on PlayStation 4 is a 43.6GB download file. Many users are stating that the auto-download date is currently listed as October 30 – stay tuned! (second image via @)
We just got sent over an image of the back of the Call of Duty: Black Ops 3 Hardened Edition (French version). The box shows that PlayStation 4 customers need a min of 55GB of hard drive space for this game.
Thanks @Kalijvc for the tip!
