360 lost another exclusive 
I just finished the PS3 version of Bioshock and once unlocked, in the extras there is a 15 second trailer for the sequel.
Confirmed title is Bioshock 2: Sea of Dreams and the trailer shows a grown up little sister holding a big daddy plush toy, while sand of buildings in Rapture rise from the sand. It's set on the Atlantic Coast.
Other pictures I took:





Update:
Here's another 2 pics to show it isn't fake. ( *spoilers* )

The two screenshots at the bottom contain story spoilers. If you haven't played any bioshock yet, don't click them to see the trophy list.
