A Neogaf user recently posted a patent drawing that shows what appears to be a charging dock for the Wii U controller.
Judging from the patent, the design would work in the same fashion as the Nintendo 3DS charging dock. In addition, the design of the Wii U controller looks unchanged from the version we were introduced to at E3 2011. No surprise, but Nintendo could easily make some alterations.
So, if the Wii U controller will need a charging dock, does this solidify the possibility of only ONE controller being used for one Wii U console? Discuss!
