I honestly have no idea where the line is. Why shouldn't you call for the cost of PS4 to be included since it is also required? Is it just because you have one and not the other? I have both, so it shouldn't be included for me because I don't need two.
It is easy. If the VR headset needs X Component to work it should be included in the package. This is not a power cable or headphones or a controller. This is a component needed to actually be able to use the headset.
Some people already have cameras.
A lot of people bought the camera. A lot of people sold it because they had nothing to do with it which is how I got mine. But it should still be included if it is needed. How hard is this to understand. It's like if you bought a PS4, you were happy it was $399, only to find out that no controller was included.
I have a camera plus 2 move controls so the price of VR is $399 for me (well $550 CAD). I would hate if they priced it at $499 and included the move controllers plus the camera because why would I want an extra camera and controllers?
In your case it is more than $399, but for all the people that already own a camera, why should they have to pay an extra cost?
If you think that Sony should list the most expensive price, that's just not how it works. Similar to when the PS3 launched, they listed the price of the 20gb model, even though the 60gb model was $100 more.
I already have the camera, bought it used because although they sold a lot, many of them were sold.
Please try to understand the argument from the point of people wanting to get into VR. You and me we have the camera, but are a minority. It should have been us asking for a bundle without a camera/Move not the other way around.
If Sony says PS4 camera is needed 100% to use the VR set and does not included it in the set, does not even give a lot of attention to that, then it is dishonest. Like you say Sony only aimed to list the cheapest price, but in the example you gave both console worked completely out of the box so it makes sense. Here you NEED the camera, no way around it at all. All the people that got the camera should be given the option to have a bundle without it, but there shouldn't be only one bundle without one of the main components included.
They're gonna announce Camera/Move bundle if that's what you want.
And I have high hopes this is true, but it is dishonest IMO to announce it as $399 when you actually need that extra camera.
