In an interview for the latest issue of Games for Windows Magazine, Levine stated:

"Diablo II, to me, was a great model for an expansion, because it enhanced the original game, but also extended the game, too. I’m not a really big fan of expanding things just by linearly adding to the experience, adding a new campaign, as much as I am of enhancing the original experience and adding replayability to that experience. I think that certainly BioShock’s combat experience is great, but it could be broader. I’m a little more confused as far as how to expand the narrative experience."

It’s good news for BioShock fans. Still it would be interesting to see how will the developers manage to add DLC into the mix, given the fact that the game doesn’t feature a multiplayer option and just adding extra levels would be a real stretch due to the current story.

Also, it would be interesting to see what price tags will come along with the new content.
