I think it's a tough call. X1 sod 3.5M more units in 2014 (doubling the Wii U). This years I think Wii U may end up down YOY, while X1 will probably be up YOY by a good amount, increasing the yearly gap.
I think the biggest challenge is that X1 would have only one holidays season in these timeframe to do it. Q1 2017 would be easier. But I wouldn't count X1 out of these fight, it can do it.
