Where did you get your Black Ops 2 sales from? Vgchartz has it at 51k for week 1 which I'm pretty sure is overtracked since NPD had it at about 21k-ish.
Your prediction.....
"So Black Ops II has had a good start in the US, based on history. My resulting worldwide prediction for BO2 WiiU? 4 million."
Really dude? Even if you were talking worldwide sales that is just not going to happen.
