Bethesda confirmed the North American release dates for the PS3's long-overdue Skyrim DLC expansions today. Dragonborn is first up on February 12, followed by Hearthfire a week after on February 19, with Dawnguard finishing things up on February 26.
As Bethesda announced last month, each expansion is going half-off during the week of its release, although the publisher has yet to announce specific prices. Meanwhile, the PC release of Dragonborn is scheduled for February 5.
