This holiday, the Wii U, Nintendo's upcoming game console, goes on sale. The Kyoto-based game maker revealed the machine last summer and continues to provide new details about the consoles; however, there is still so much that's unknown.
Nintendo's Wii U patent fillings recently surfaced, providing a look at what the company was planning. The documents are from Sept. 2011, and they do clearly point out "statements herein do not correspond to any particular actual product that may be eventually be made available to consumers." That means what Nintendo filed might not make its way into the final product.
