Prediction: Xbox One Will Have a 10 Million Lead over Wii U by the. End of 2015

[Shootdatrupee]

Uh nope. Only way Xbox will significiently overtake at the current rate is if Xbox has a life about 2-3 years longer than the Wii U.
Which it likely will, but that just means overtake and lead of 10M by end of 2015 is impossible.
