The pricepoint of Oculus Rift has concerned many people after today's announcement, many now believe that VR won't become popular due to the price for a VR device + a PC capable of running said technology properly. Now we have to see the price of Sony's VR device, but beeing realistic we can't expect anything less expensive than 299$ (imho 449$ at this point but who knows) but still adding to that the 300$ for a PS4 we still have a 600$ price, that isn't appealing for the majority of people.

Taking all of this assumptions into consideration we can see that there's a possibility for VR to bomb at it's current state. So I was wondering,in an hypotetical future, knowing that Nintendo previously failed with the Virtual Boy and that Oculus and Sony failed during this generation, do you think ANYONE would try to work on VR to make it appealing to the crowds ?

Yes. When it becomes cheaper and accesible to the masses.

When VR becomes cheap enough to be price just as an add-on, instead of a whole new console, then it will become popular and accessible enough. 200€ should be a good enough price.

i think psvr will do well , it has a good support from first and third parties , and a large install base
but not many peaple will buy a ps4 and psvr at the same time , the existing ps4 owners will buy the psvr

Yes. But seeing as one word posts are considered spam, I'll have to write more than one word. Which I now did.

The more time passes, the more accessible VR gets, because the tech will get cheaper.

Even if fails, it will be tried again when the time is better gor it.Currentlu, the tech is top expensive and somewhat limited.But it will ceartanly rise again.

VR is the future, but maybe the future isn't now.

VR must become even more practical and affordable for it to appeal to the masses and have better possibilities at success.

So something that does what it says well, or the opposite where it is cheap.  First stage of brand new tech's life.  Cannot have it both ways. 

If companies expectations are low in short term and the sales are like they expected can we call it a success?
