Which one will make it to 10m first, Wii U or Xbox One?

Wii U. Like you said, the XBO is barely outselling the Wii U as is, and while the XBO has Titanfall, the Wii U has Super Smash Bros and Mario Kart 8, two franchises that are bigger than or equal to Halo. Maybe the XBO will eventually outsell the Wii U but as for reaching 10m first, that's all the Wii U.
