I have recieved the disc version last saturday and it did download a 28 GB file right from the start.
In the main menue of the game it says version 1.1 but in the Playstation download history its says
"saturday: 28 GB - version 1.02".
I have a friend who owns the Steam version and he says that its version 1.2 in his main menue.
So i have no idea whats going on …
