What's more, it'll be fully integrated into the game rather than siphoned off from the main menu. Console gamers who buy it as DLC will be able to use their existing character, though they'll need to have progressed quite a way through the story before they can access the extra areas.
Sounds like "fully integrated" means "new default warp bonfires" for the Lordvessel.
Fair enough, I guess. It's not like they can re-write existing areas with new branching points.
