Over one million downloads of the demo is mightily impressive.

Dont get to excited about the sequel though.  They say they "obviously have a new franchise on their hands," but also that they expect a three-year development cycle for the next Bioshock IP

Already a thread about this.

Oh Dear God! I REALLY hope they don't make a BioShock 2, The game wasn't made for a sequel. Leave the game as is and work on something new, don't ruin the game by forcing a sequel on to it. All a sequel will do is destroy this already perfect game.

I'd love a sequel. I think they already set it up for one. But I don't want to say and give anything away for those that haven't played it.

Hopefully BioShock 2 will have some pirates in it; everything is better with pirates.

Maybe some ninjas thrown in for good measure, too.

hey, pirates+ninjas, it remembers me a game !!!

 So long as its not Jack Sparrow that is... His face must  be among the most  shown and viewed globally...

PS: Were there some kind of ninjas in Half-Life, or am I confusing that with something else? Some sniper creatures in a room filled with containers or something. 

On a more serious note, how awesome would BioShock 2 be if it was a prequel that takes place during New Year's Eve 1959?

Bioshock 2 is certain. Take 2 can most of its assets back into use and whip out a multiplatform game within 9-12 months. An Exclusivity agreement might net it a few million $$$, which it requires badly.

 We have a winner.
