We are not satisfied yet with Dawnguard’s performance on the PS3. We would like for everyone to have a chance to play Dawnguard, but we aren’t going to release it for PS3 knowing that some people’s experience in Skyrim will be worse. We do everything we can to have our content available to all; from our free updates, to user mods, to paid DLC. We’re as disappointed as our fans when that isn’t the case, but we’ll continue to push for that reality.
It was the PS3 holding the release up. Four years later and company's still have problems porting and developing for the system. I guess I owe the news sites for complaining why it wasn't out yet on the pc after 30 days.

Well they claim it's a mini expansion but it's just as big as Fallout NV DLC.
