I think 1.5m- 2m range but Wii U just staying alive. This year, expect X1 to pass the Wii U WW for about 2-3 weeks after Destiny, and after Fifa(for EU not Global total though I think) and Cod. But Smash comes out and maybe not even that Halo Collection will make X1 sell more than the actual Wii U Weekly and launch week of smash sales.
But 2015 will be the epic duel lol.
