Fallout 3 Interview

The Bethesda Blog is pointing to a new Fallout 3 and Broken Steel-related interview with PR representative Pete Hines over on SPOnG.
SPOnG: Following the release of Broken Steel, will we see more DLC for Fallout 3, or is this the end? Any chance of a Shivering Isles-sized expansion?

Pete Hines: No plans for a Shivering Isles expansion. We just felt like it was better to focus on the kind of DLC we've been doing as opposed to something that takes so long to make and comes out a year later, like Shivering Isles did. This is the last of the three we had announced we wanted to do, no announced plans beyond that.

SPOnG: Will there be enough quest experience to be had in Broken Steel for players to level up to 30 without having to grind on pre-DLC quests/enemies?

Pete Hines: No, probably not, and that wasn't the intention. The intention was to remove the level cap so that if you have Broken Steel, regardless of whether you want to play that quest or not, or you want to start a new game from scratch, you can continue playing beyond level 20. Again, fans wanted to be able to take their characters to higher levels, so we included it. But it is not specific to the length of Broken Steel, at all. It is a very long climb to get from 20 to 30 and you'll need to do a LOT to get there.
