Playing Skyward Sword for hours on end, I would have to constantly buy and swap in new batteries. Soon becoming too much of a hassle, I picked up a pair of rechargeable batteries and began using those. Recently, a mysterious patent showing a type of stand or charger for the Wii U controller was discovered, which will perhaps eliminate the nagging hobby of constantly replacing batteries. Furthermore, this mysterious peripheral may double as a convenient stand while the controller is not in use.
So many rumors, so little time until E3.
