User blog comment:Gearslover01/Possible Easter Egg for new BioShock game?/@comment-2250991-20130705170719

Personally, I don't think it was meant as a "next game" easter egg, as much as it was a cut from a alternative ending, or that it was meant to be in-beween the Sea of Doors sequence in the game. If you remember the dialog before reaching the Sea of Doors, they discussed about those "stars" in the sky. This obviously looks like a Observatory with distant cut out lighthouses above it, which aspects of the dialog could apply to this as well. Still, this is a good find, and hopefully, may be something re-added for story-based DLC.
