If the AVP were cheaper, I think you'd have a lot more people willing to use them together. The social features are useless if nobody owns one or wants to use one.

You'd also have more of a critical mass of people with accessories. A used market for lenses and accessories, people with spare batteries about, etc.

Not to mention an app ecosystem. For every person like me lamenting what could be, there are a dozen people with more mainstream desires, like Instagram 3D or Temple Run 3D or whatnot.
