Hartmann's statements come less than a year after was officially announced in March 2008. BioShock 2: Sea of Dreams was first unveiled to the world in the form of where a Little Sister holding a stuffed Big Daddy watched a suspiciously Rapture-like metropolis made of sand rise out of the ocean.

Hartmann reveals how we may see BioShock 6 eventually, saying that "if we spin it the right way and get the right twist of innovation, we can make six parts of it, as Star Wars did."

The company's president also talks about how they won't be cashing-in on BioShock's popularity because they don't want to ruin the series for fans as the Matrix did.

"For BioShock, because it's so story driven, the question obviously arises: how long can you do it without turning into The Matrix?," says Christoph Hartmann.

"The first Matrix was great, the second one was weird and the third one, you thought: 'Who [making this] is on crack and who isn't?'."
