A video was recently leaked to Youtube that showed what appeared to be a teaser trailer for Bioshock 2: Sea of Dreams. Although the user has taken multiple pictures and a video, one still have to take this with a grain of salt until an official announcement has been made. For those of you with early copies of Bioshock on the Playstation 3, you can supposedly find the video under the "extras" menu after beating Bioshock.

You can check out the video below.
