Consumers who buy the PlayStation 3 version of specific PlayStation 4 titles will be able to pick up a digital edition of the next-gen game for a "significantly discounted" price, president and Sony CEO Andrew House announced at its Gamescom press conference today.

The limited-time discount will apply to Call of Duty: Ghosts, Watch Dogs, Assassin's Creed 4: Black Flag and Battlefield 4. It's unclear how much the discount is worth or how it will work.

"We see this as a great way to reward PS3 gamers for their loyalty when transitioning to PS4, ensuring that it is as simple and accessible as possible," House said. "Activision, Ubisoft, EA and Warner Brothers are the first publishers to commit to this and over the coming weeks and months, we look forward to sharing more information with you.

Similar deals are currently being offered for Xbox One and Xbox 360 through retailers such as Amazon and GameStop. Under those offers, consumers can upgrade to a physical copy for $9.99 on titles such as FIFA 14, Call of Duty: Ghosts and Assassin's Creed 4: Black Flag.
