1-1.5 million is my guess. As others have said, Xenoblade WOULD have sold more had it been released closer to the Japan release (especially in America) instead of waiting until Wii was basically done. If it becomes the same kind of critical darling as Xenoblade, it should do well amongst the hardcore, and especially since it'll be releasing AFTER Wii U has had a chance to hit it's stride following the steady stream of 3D World, Donkey Kong, Pikmin, Wind Waker, Mario Kart, etc., yet still early enough in Wii U's lifecycle to enjoy some time on store shelves (unlike Xeno which was only available at Gamestop or online from Nintendo in the US). SHOULD do better than Xenoblade, but will depend on whether Wii U's install base reaches healthy enough levels before its release next year.
