The PlayStation 3 version of The Elder Scrolls IV: Oblivion will not have downloadable content available when it is released, even though the Xbox 360 and PC versions did.
Pete Hines, PR Vice President of Bethesda said: “You could point to any number of factors for why that is. Although it's impossible to say which is the better between [Xbox Live, PS Network], Xbox Live is easier to implement because we've had a much better sense of it at an earlier stage than with PS3”.
The company did say that it’ll be releasing extra content for the PS3 version of Oblivion at a later date.
