Why I think Bioshock infinite will be about time travel. Or at the very least there's some odd connections between the Bioshock and Bioshock infinite. Also given the hush over most of the game after the 4 hour make I imagine this is to cause peoplel ike me to write blogs like this so that people like you get interested.

Quiet simply it has big daddy in it which wouldn't be much at all but the level they chose for big daddy is Bioshock infinite. Why not do Rapture? Maybe its just to market or Maybe big Daddy and some other things are tied into it. I don't know anything for sure and this likely will have no bearing on the game whatsoever. It's just something I found interesting.
The game was originally supposed to be released in 2012 the game takes place in 1912. Since we as humans like big round numbers to jump to whenever we deal with time travel something tell me that the end of the game may take place in the future.

Now the more interesting part.
Why do this?
As far as devices to show change Time Travel seems like the way to go. If you look at the consequences for your actions in Bioshock the game was vastly the same outside of the bits of time where you harvested little sisters or not. There are two political powers vying for control and since this is at the start of a Similar scenario to Rapture.
The more interesting dynamic would be being one of the people that shaped rapture into the kind of city you saw at the start of Bioshock. It would also allow more of the shootout that happen in FPSes to make more sense because while the play may be in combat a lot if their jumping through time for everyone else time has passed. There's room for things to have happened in the wake of the player instead of just the next room.
I do think no matter what happens that Levine and company are working at pulling something interesting with their game. I just hope it pays off. At the very least you can't fault them for not being ambitious enough.
