For some time now I think one of possibilities for next Nintendo home console is them trying to pull another Wii - one of the paths might be console with 3-4x WiiU power + VR glasses for $250.

What I will say is this ... Miyamoto seemed to hedge on the VR issue a bit. At E3 last year he said while the tech was interesting he didn't like the alienating/non-inclusive (Nintendo believes in the family gathering around the TV to play) aspects of VR. 

But a few months later, Nintendo patented head tracking glasses, while not exactly VR ... it sort of was a step in that direction.

When asked about VR again last October (more recently), Miyamoto was curiously less talkative ...

What next? At the mention of the rise of Oculus Rift, Miyamoto looks guarded: he likes the idea of virtual reality, and previously experimented with the technology in 1995, with the Virtual Boy, but was worried by the manner in which players hunched over the apparatus: “It didn’t look beautiful to me,” he says, “which was something of a concern.”

As to whether Nintendo are developing a more elegant version of the technology, his lips are presently sealed. “I have nothing to tell you about Nintendo’s involvement in virtual reality. We have nothing to announce yet,” he says.

The we have nothing to announce ... yet part kinda stuck out as interesting. Maybe they are working on something VR related, though this DeNA thing may have nothing to do with it. Then again ...

That patent is actually just headtracking hardware, not necessarily glasses. It was used in the New 3DS

Also it was patented a while back, the patent only surfaced a few months back.

Do u know when it was patended?

Can't remember exactly, but I remember it was at least a year before it surfaced.

I just looked it up, it seems like they filed it in March of 2014 and it became public in July 2014.
