Dragon Age: Origin's Return to Ostagar downloadable content was scheduled to be released on the Xbox 360 and PC today, with the PS3 version coming later in the month. However, last night that all went up in smoke as the DLC were delayed indefinitely for all platforms.
Community Coordinator, Chris Priestly, last night announced that the DLC would not be released today on the BioWare forums. "We’re sorry but the planned Return to Ostagar downloadable content scheduled to launch on January 5th [6th in Australia] has been delayed for all platforms. We will update you as new information becomes available."
We suspect that the content will arrive later in January, which was the window originally given to the PS3 version.
