Oblivion will make extensive use of the PS3's hard drive by caching multiple gigabytes of data, which helps with load times. Bethesda's Pete Hines has commented that recent reports of data duplication on the PS3 Oblivion disc have been exaggerated, and this technique isn't different from the similar strategy that was employed in the creation of the Xbox 360 game last year. Lastly, it's unclear if or when the PS3 will see the Shivering Isles content that's on the way to the PC and Xbox, though with a burgeoning PlayStation Network and plenty of unfilled hard drive space, it's not hard to imagine the expansion can be made available to PS3 owners somewhere down the road.
