To all the people complaining about going back to Rapture:
-It's still a hell of a lot more original than going back to Normandy, the Middle East, or a space marine colony.
-We might not even go back to Rapture. One of the newsclips talks about Ireland having its own bigfoot, implying the Big Daddy(?) is staying on land. Plus, how could he kidnap the Little Sister(?) and take her back to Rapture if she didn't have a diving suit?
I'd like to see a little of both worlds. Maybe it'll start on the surface, hunting the kidnapper, until the player eventually tracks the Big Daddy to a bathysphere that takes him down to Rapture. AFter all, Bioshock just isn't Bioshock without a failed underwater utopia.
