Sorry, gamers hoping to get to the thousand hour mark on The Elder Scrolls IV: Oblivion, your chance to log more hours post-Shivering Isles expansion will have to be done with familiar content. In a quote from 360 Gamer Magazine, Bethesda Softwork's Peter Hines reveals that the Shivering Isles expansion will be the first, and last, expansion for the time-swallowing RPG.

I guess they don't count the Knights of the Nine content as an expansion proper. Still, I think we can all absorb this knowledge comforted in the fact (okay, speculation) that Bethesda is hard at work on The Elder Scrolls V. Michael McWhertor

No more expansion for Oblivion... [OXM]
