- They don't know how much it will cost.
This is mostly true, consumer model of the Rift is expected to cost about $300.
- They have yet to see a game that makes it seem worth while.
Also true, but this won't happen until a game type is found to work well with VR.
- They can see there is no major publisher support at this point.
Facebook?
- They have spent too much money on useless gaming peripherals in the past.
Doubt it, not everyone purchases every gaming component. You'll see further adoption once it starts becoming mainstream.
- They don't know if it will work well with their PC/console.
If the user has a PS4, they're set with Morpheus. I don't see PC changing much in terms of 'Will my game work or not?'
- They feel that since it is an item you wear, if you have three people in your house you need three headsets and that comes back to the cost issue.
Somehow this doesn't stop multiple Nintendo 3DS or PSP purchases in a household.
- They don't know what the final build quality will be like. (Maybe they break within three months of purchase).
I've never heard anyone ask this before.
- The type of games/media they enjoy will not translate well to VR.
"May", please don't assume all existing games will not move over VR without modifications. There are other games which can be explored thanks to VR Tech; such as Keep Talking and Nobody Explodes on Steam.
- They own only a Microsoft or Nintendo console, which do not support VR.
This is true, but you're forgetting about cellphones which many people own.
- They get motion sickness from VR.
Motion sickness falls on the developer. If they're not taking into account player momentum, presence, rendering in stereo or not, resolution & frame rate (1440p@75fps). The user can experience motion sickness from playing in VR.
- They haven't tried it and won't try one because it is really gross putting something on your head that someone else just had on their head.
Somebody needs to learn how to keep their headset clean.
I could keep going, but there are a litany of reasons why a person might presume that VR MIGHT not be the future.
