Dat poll....
Clearly Nintendo is going to stay on top. With Wii U consistently outselling the X1 each week, the gap is going in the wrong direction for Microsoft and to say that they'll be able to not only close it but to surpass that gap during Nintendo's busiest time of the year, with Mario Kart and Smash Bros and Amiibos to help sell it, is just wrong.
It ain't happening this year, and I'd be surprised if it happened before Nintendo unveiled the Wii U's successor.
