This is all a bit silly, going around in circles over something as simple as a subtitle, but there's a record that's got to be set straight: Bioshock 2 is still "Sea of Dreams".
You can forget those reports from last week that explicitly stated "You won't be seeing ‘Sea of Dreams' moving forward, just ‘BioShock 2". Just forget all about them. 2K didn't really mean it, and have today stated that the game will still be called "Bioshock 2: Sea of Dreams".
Just as well we didn't go on record saying the name was stupid, and...oh.
