CVG have reported that there will be a surprise Bioshock announcement this weekend, the story which was originally taken from Kotaku states "Irrational Games is set to make a surprise Bioshock announcement on US telly this weekend, alongside a brand new trailer. "You won’t want to miss this!," US tv show Game head promises".

There’s only one week left until it’s release so what this announcement could be is beyond us, Kotaku have recently advised that Bioshock is exclusive to PC and Xbox 360 so we really don’t think it could be an announcement of a PS3 nature.

Whatever this announcement is, we will let you know as soon as we possibly can.
