Well that would depend on what it does, doesn't it? We know absolutely nothing about this product. We pretend to know a lot about it.
If this product allowed me to magically have a virtual Mac display of any size and resolution I want and it was so good that I could use it as a total replacement for desktop monitors.....sure maybe that is worth $2K.
Considering Apple is an antonym for gaming, and VR's only real world commercial application today is gaming, it's hard to imagine that Apple is even working on this product.
