One of those patents, as you can see in the diagram above, is clearly related to VR in someway. It shows a headset with a slot where another device can be slotted in. In fact based on the previous patents that clearly are about the Switch, it seems that this device in question is the Switch that will presumably power this VR headset.
However patents are merely ideas that companies such as Nintendo want to protect, or at least file away and use for another date. This doesn’t mean that the Switch will have VR capabilities. However in the past Nintendo has stated that they are looking into the technology, but whether or not this manifests itself in the Switch remains to be seen.
Based on the reveal trailer, there have been no indication to suggest that VR gaming is one of the console’s features, but perhaps it could be added at a later date. In the meantime Nintendo’s Shigeru Miyamoto stated that one of the priorities is that VR should be safe for kids, and whether or not Nintendo has figured that out remains to be seen.
