Bethesda announced that the third add-on for The Elder Scrolls: Skyrim will arrive on PS3 and PC early next year. This will be the first download add-on released for the PS3 version after over a year.
Problems arose one year ago, during the launch of the first DLC: Dawnguard. Due to technical issues none of the available content packs are playable on the PS3. Bethesda said that they are working with Sony to deliver all the DLCs to the system, and that this is not an easy task.
Meanwhile, Dragonborn releases today on Xbox 360. So you can grab it right now.
