The dark satanic rumour mill suggests that the former playing card maker is determined to fix a problem which has dogged other VR machines on the market. Basically after you have worn a headset for half-an-hour you get tired and a bit sick.
Nintendo's acting representative director Shigeru Miyamoto told shareholders that the company was "researching VR" - but didn't want to show off the NX at E3 as they wanted to "avoid imitators."
The research appears to be focused on coming up with a way that the headsets can be deeply immersive without turning the player into Linda Blair from the Exorcist. But it is clear that Nintendo does want to incorporate VR into its hardware once more.
It must think that it is likely to do better now than when it tried to in 1995 to run the Virtual Boy.
Apparently it will have a machine ready to show off in March next year. If it manages to avoid the VR fatigue then it might be onto a winner.
