I'm not Nikon mirrorless savvy, but some of the cameras are available in Target stores and other local discount stores and Costco.
They are everywhere.
Personally, I don't know who their market is. An interchangeable lens market seems dubious here in the US, if you're looking for a wide-spread base(the world market could be very different).
It seems to me that Nikon should have joined the micro 4/3ds gang. That would have made a ton of sense. I have a Panasonic GH2 that I use my Nikon lenses with now, and use it for video with those lenses, and it could be a terrific backup, too - but I really have that taken take of with another body.
Four thirds makes more sense than the Nikon format. I would think Nikon would dominate the lens market, should it want to, and body market, if it jumped it.
The V/J bodies don't seem to be much, if any, smaller than the Oly bodies, and a little engineering would have really shored up that somewhat fragmented market. As it is, Nikon has dominance in the Asian markets, and dominance in the shelves in the American markets - I'm guessing that's why the price is dropping and will continue to drop until the there is a small drop in inventories.
Hopefully, Nikon will step into Micro 4/3ds, but I really doubt it. I think it is a case of corporate ego.
