Why would u want a controller that you can't replace the battery or battery pack because if the battery dies before the controller breaks you have replace a perfectly fine controller....
Not being able to replace the battery is one of the biggest complaints about cell phones....
Wii U is doing OK considering Nintendo was making $100 per unit when it was released and Nintendo is still making a large sum of money on each Wii U and game they sale...
A lot of the products are Nintendo so that is a lot $$$.
Not making much on licensing on the Wii U though...
