On Bethesda's official blog, they have announced that new downloadable content for their RPG Skyrim will be released for the PC and PlayStation 3 in February. The DLCs include Dragonborn for the PC and PS3 with Hearthfire and Dawnguard upcoming for the PlayStation 3.
The DLC for the PC will be released on February 5th, will be available on Steam, and will include the English, French, Italian, Spanish and German versions. For the PlayStation 3, they did not specify a specific date but stated that following the Dragonborn release in February, PS3 users will see a release of the Hearthfire and Dawnguard add-ons.
They also mentioned that all of these will be available for 50% off during the the first week of launch, so I'll keep you updated when they hit the market so you can save a little cash by buying them in that period.
