Coming from a Yahoo interview with Shigeru Miyamoto...
"The current types of virtual reality aren't really a good fit for Nintendo's philosophy of trying to create entertainment that people can play together in the living room. We're constantly looking at different technology and experimenting with different elements of it, but we're not feeling virtual reality is currently in a place where it's ready to be released - as a product that fits with our philosophy of fitting in the living room.
We're here at E3 this year to really focus on the games that are launching within the next year or so. We're not showing off or showcasing anything that's further down the road, and that's why you don't see us here with any samples of potential virtual reality type experiences."
