You can put just anything on the market and at any price and you sell it. Just, it will show in the upcoming month if the amount you will sell is what you expected.
I do not think that Nikon will reach it's goals here. We are in a period and a state where Mister everyone can afford a good camera and many buy those supposed to be for Pro market, despite of the fact that the only advantage of this cameras is there bulky and solid build and can often do much, but really much less then most pro-sumer cameras that offer a better and more complete image processing making quite often a computer rework useless.
What is ball-playing game in this case is that the D3x was ready made since the beginning and all Nikon had to do is insert the sensor in the D3 body once it was ready to ship to them and put the same camera with another sensor on the market. The price difference justifies nowhere and it is a fact that the camera could have been offered as an alternative or better a performance/needs relation to select from between the both cameras without even a cent of difference in price.
Here it is obvious that Nikon plays a rotten game. For sure, those smart brains that need always to be the first to have the new baby and this just at any price and have the wallets that make them care a f---uzzy about the cost exist and will buy it. But, those served, who comes then. In studio work a Sony A900 offers same good shot and is half price, lens included.
The D3 went down from initial price quite fast, today it's an old gear that is somewhat behind it's small brother for almost 75% of it's features. Now the same old box shows up with a high pixel chip and fantasy price.
I think we don't need a boycott and tere has not been any and there will not be any. Want it, buy it and pay. Don't want it leave it where it is. I think the answer to this question will be found inside of your wallet only and Nikon will find out soon that this nasty game doesn't pays anyway, specially not for an item that turns to throw away stuff in less then 2 years and you will sell for 30% of it's initial price and, not to forget, another or more other similar cameras to select from and that sell for less then half price.
Let the guinea pigs buy it, test it and when the next body comes out and it can be bought less then half price, buy one, it will then still make the same good shot.
I have not found any advantage to a full sized until now, have not found a relation to picture quality/price with more recent cameras and just paying that much for a bit of AF and useless gadgets, no thanks.
Carpe Diem
