Judging PSVR is pre orders there is a market for it. Although I highly doubt that is the market Nintendo should be targeting. PSVR is probably going to be a succes especially if they support midware pc's as well due to the fact it is from Sony instead of an unknown hardware maker. Nintendo on the other hand shouldn't do VR purely because Sony does, they need to launch a PS4 like NX for $250- with strong third and first party support to become relevant as primary console again so that NX2 can compete against Xone and Sony. This way they provide games for young and old, while PS and MS are targeting mostly adults. They might not do as well as PS, but 50 million would be plausible and I consider anything above 50 million not a failure.
Please excuse my (probally) poor grammar
