Consumers who buy physical version of the supported games will find a code included in the game case, and, at the cost of $9.99, gamers can upgrade their games from the PS3 version to a PS4 version via PSN download. The only catch, apart from the upgrade fee, is that the PS3 game disc will be necessary to activate the PS4 version once the PS4 launches.
The four supported upgradeable games are:
-Assassin's Creed IV: Black Flag (Jan. 31, 2014)
-Call of Duty: Ghost (March 31, 2014)
-Watch Dogs (Jan. 31, 2014)
-Battlefield 4 (March 28, 2014)
