Battlefield 3 expansions to arrive one week earlier on PS3

Not unlike Microsoft and Activision's agreement to give Xbox early access to Call of Duty DLC, Sony and EA have arranged for Battlefield 3 expansions to arrive with an exclusive lead on PlayStation 3. However, Battlefield 3's expansions will stay exclusive to the PS3 for a shorter period: one week per expansion.

The deal kicks off with "Back to Karkand," which launches "later this year" and brings with it four Battlefield 2 maps (including Wake Island) rebuilt in the Frostbite 2.0 engine. The expansion comes free with first-run copies of Battlefield 3 for all platforms, though it now seems it won't be available for download immediately.

The Battlefield 3 beta opens on PC (check the system requirements), PS3 and Xbox 360 on September 29.
