Got a tweet from the developers over at Bioware, with some information.
After being pulled last month, Bioware will release DAO: Return to Ostagar for the PS3 next month. It recently passed certification and received the date March 11 to hit consoles
The Xbox 360 and PC version already passed certification and will be released at the end March.
The expansion pack hits stores just days after this bit of DLC, March 16th to be exact.
