Players that own Call of Duty: Ghosts on PS3 will be able to purchase the PS4 version for $10, €10 or £10 for a limited time, Activision announced today. This follows Sony's announcement last night that PS4 games will be offered at a "significantly discounted" price - also for a limited time - to those who already own the PS3 version. Sony didn't mention a specific price at the time, but the $10 point lines up with retailer next-gen upgrades.

Ghosts, Assassin's Creed 4: Black Flag, Watch Dogs and Battlefield 4 - and specifically the publishers Activision, Ubisoft, EA and Warner Bros. - will participate in the PS3-PS4 upgrade program.

Player stats from Ghosts will transfer from PS3 to PS4, Activision previously announced.
