Sony announced a new PlayStation 3 to PlayStation 4 upgrade program during its Gamescom media briefing today.
As part of the promotion, gamers who buy Assassin's Creed IV: Black Flag, Battlefield 4, Call of Duty: Ghosts, or Watch Dogs on PS3 can purchase a digital version for PS4 at a "significantly discounted price" when it launches.
Electronic Arts, Activision, Ubisoft, and Warner Bros. are all participating in the program. The promotion will be available for a limited time, Sony said, and it is not clear if the program will be offered worldwide.
The PS4 launches November 15 in North America and November 29 in Europe. The next-generation console will be available in 32 countries in all by the end of the year.
The Xbox One releases in November for $500. A specific launch date has not been announced.
