The recently unveiled Xbox 360 and PC Oblivion expansion, The Elder Scrolls IV: Shivering Isles, will also hit PS3 this year, Bethesda has said.
According to the developer Shivering Isles (due this spring for PC and 360) is about one quarter the size Cyrodiil, where Oblivion takes place. There'll be plenty to see and do but it's not just another gate to Oblivion: "Oblivion is made of lots of planes, one for each Daedric Prince. Oblivion featured the fiery realm of Mehrunes Dagon. The Shivering Isles is the realm of Sheogorath, the Daedric Prince of Madness. It's a place unlike anything you've seen in Oblivion," says the developer.
The good news is that Bethesda plans on a PS3 launch but whether it'll come bundled with the original, currently due for PS3's launch, remains to be seen. "It is our intention to make it available for PlayStation this year, but no release date has been set."
Expect to get around 30 hours of gameplay out of Shivering Isles. And before you ask, yes you can back and forth between Oblivion and Shivering Isles with your character whenever you like.
