I'm tagging this, but also another tip about Borderlands. It is only available as a part of the bundle this week, and it will be a solus game starting next week.
So you all might wanna revise your numbers, as the game cannot sell more than the console (only less if someone decides to pick up an old model).
It would not be fair for me to win because I kept silent about this.
EDIT: I will post my predictions on Monday when I get to work, I'll have more time to make an educated guess.
