Nintendo's new console the Wii U will indeed support 3D if you have an appropriately fancy television, company president Satoru Iwata has told Mercury News (via CVG). However, as most people don't own a 3D TV, and many cannot comprehend why you would want one, Nintendo's not pouring too many resources into it.
"If you are going to connect Wii U with a home TV capable of displaying 3-D images, technologically, yes, it is going to be possible, but that's not the area we are focusing on," Iwata explained.
"When it comes to 3-D, we already have the 3DS, and each owner of the Nintendo 3DS is capable of viewing 3-D images. However, when it comes to the home console, it depends upon the availability of 3-D TV sets at home, which, unfortunately, is not expanding enough. And rather than pouring a lot of energy into that kind of area, with the Wii U we'd like to focus more on each Wii U owner being able to have an equal opportunity to enjoy it."
