Hold your horses, read that headline again; it is only the Ultimate Edition of Injustice: Gods Among Us that can be upgraded from PlayStation 3 to PlayStation 4.
The PS3 version of the game, which launches on November 29th, the same day as the PS4, will have a PSN code that will allow you to upgrade the disc version of the game t a “special price”. If you purchase the game digitally you should be able to buy the PS4 digital copy as soon as it hits the store.
Warner Bros. surprised everyone by announcing the Ultimate Edition for PC, Xbox
360, PS3, Vita and PS4 but not Xbox One.
Injustice replaces Watch Dogs which has now been removed from the upgrade program, presumably because of the recent delays to the game.
