It's called 'the snowball effect.' One piece of information grows into something greater than it was ever meant to be. This effect can take hold even when the information is incorrect to begin with. This was the case when the PlayStation UK site claimed a special Move device was being released alongside the PS3 version of BioShock Infinite.

"My understanding of what happened with that was some marketing person at Sony said, 'Oh, I think there's a Move peripheral for this.' And they put it out there and we saw it and were just like, 'Uh. Really? We never heard of that before," Ken Levine told me last week.

Levine admits that errors like this happen "a lot."
