Honestly I can't see how people are being this optimistic about PSVR. This whole thing just reeks of how the Vita started out and don't even get me started on the price. 

As for NX who knows at this point we have little to no information on the what it even is. 

NX.

Psvr will do really well to sell 1-2m units in 2016. Unless Nintendo unveil a toaster 2m is the absolute minimum the NX will sell in Nov/Dec

Right now I'm leaning towards the VR

The NX should do better than PSVR easily, unless its somehow priced more. The NX will be a complete system on its own, whereas PSVR is a peripheral.

Also, I honestly don't think Sony expects more than a couple million sold within the first year. Nintendo, on the other hand, probably expects much more of the NX. So, PSVR selling more than the NX somehow would be a terrible result for the system.

PSVR definitely

Uuuh, tough question. But considering we don't have precedent for VR headset sales (specially on console), and we have no idea what the NX is or how people is going to react to it, anything goes. I'll just say NX, because just a console is easier to get than an add-on.

Not sure until I get more info on NX.

NX will have Zelda

what a Weird question... if NX doesn't sell more than PSVR Nintendo are in trouble.

I voted PSVR. There'll be over 40 million PS4 owners by then.

On the other hand, if NX manages to recapture some of the Wii's lost audience, or engage a completely new audience, then who knows...

Assuming they both launch at the same time, of course.
