Developer DICE has announced a timed exclusivity deal for Battlefield 3 DLC on PS3.
Starting with the game's first download, Back to Karkland, all DLC for the title will be available exclusively for one week on PS3 before it hits Xbox 360 and PC.
The deal apes that enjoyed by Microsoft and Activision which sees all Call of Duty DLC enjoy a period of timed exclusivity on Xbox 360 – typically for around a month.
The agreement is the latest in a long-line of close ties between EA and Sony.
Former EA releases such as Dead Space 2 and Medal of Honor also offered exclusive content on Sony's machine that was not available in rival SKUs.
