BioShock 2: Sea of Dreams confirmed + teaser trailer

Seems as though 2k has hidden a little surprise in the PS3 version of BioShock. Those who complete the game will unlock a teaser trailer for the sequel. That's right, BioShock 2: Sea of Dreams has been confirmed. The trailer itself is a bit of a mystery to me. It shows what appears to be a little sister, all grown up, standing near the ocean when... something begins happening. No idea what any of it is supposed to mean, but the sequel is indeed on it's way and that's good enough for me. Check out the teaser trailer below. We hope to have a better quality version soon.
