I didn't play the pc demo so I wouldn't know about the script. But I can agree that a ps3 version may have been in production. This wouldn't really be news unless a lot of people were under the impression that bioshock would go to ps3.

However, I don't think there are any wrong facts that would "recruit xbots for microsoft's army" here. It's a well recognized gaming site that did an interview with the lead designer of the game. Its not like xbox 360 propaganda. Just a case of game exclusivity.
