The PC launch falls in line with previously released Skyrim packs "Dawnguard" and "Hearthfire," while the PS3 announcement is a bit of a surprise. Although the publisher had previously stated DLC was "close" for PS3, this latest announcement only recognizes "Dragonborn." We've followed up with Bethesda for clarification and will update when we hear back.
Update: Bethesda responded to our specific request for clarification about "Dawnguard" and "Hearthfire" for PS3 by stating: "We think Dragonborn is our best add-on for Skyrim yet and we didn't want fans to wait long, so that's our current focus. Each platform takes a lot of time and attention."
