It probably won't apply to a lot of you, but if you happen to buy one of a selected handful of games on your PS3 and then want to get the PS4 copy of that same game, Sony and its partners are going to make it worth your while.

During its Gamescom press conference, Sony announced that for cross-generational games like Call of Duty: Ghosts, Watch Dogs, Assassin's Creed IV: Black Flag, and Battlefield 4, if you buy the PS3 version, for a limited time Sony will let you buy the digital PS4 version for a "significantly discounted price."

The company didn't say how much or for how long, and other details will be revealed in the future.

[Note: The story was edited to say it's the digital PS4 version.]
