Wii U ad reveals the Commercial Family Warehouse

The Wii U's advertising campaign takes us into a part of the Nintendo headquarters we've never seen: the facility where all the Wii commercial living rooms from the last six years are stored, complete with smiling families engaging in family fun and good-natured competition ... forever.

That strange mechanical whining you hear in the background is the enormous crane Nintendo uses to remove these Wii and Wii U habitats from the facility, depositing them in soundstages for Ubisoft launch game trailers. That's the only explanation we can think of for what almost sounds, at first, like music.
