I will say Xbox One.
Xbox One will do at least 30M in North America. It already did 6.5M in North America and not even 1/5 of it's life has benn reached. PS3 managed also 30M so why not Xbox One? 3DS is slowly dying out in Japan, it only did 3M last year. It will do 27M maximum in Japan.

A moment, USA, not North America.
