Seems the PC version of the game will be released alongside the console version according to Blue's News.
I purused the Bioware forums and here is what Chris Priestly post:BioWare announces a delay to the Windows edition of Dragon Age: Origins, saying the PC installment is now due in the second half of this year coinciding with the release of the console editions of the role-playing game. They do not offer a reason, but the pronouncement does include reassurances from Dr. Ray Muzyka, who says: "Dragon Age: Origins is shaping up to be quite amazing in its level of quality and polish," going on to say, "I’m really proud of our team, who are working very hard to make Dragon Age: Origins the biggest and most exciting BioWare game yet, and we will work to ensure it not only meets, but exceeds the expectations of our loyal audience of fans."
