I have been asked by some people about the price of the upcoming Sony Alpha 900 flagship digital SLR camera. The problem is that there is no information filtering down from Sony. The only thing that we can say is that there is a body of indirect evidence that points to some pretty serious competition figures.
Nikon Rumours affirmed last week that the Nikon D700 (or D700 FX) will be priced just under 3000 USD. It has been said that the Canon EOS 5D MkII should arrives around 3500 USD, but the Canon EOS 5D is already sold under 2000 USD now. And the Nikon D3 (already previous generation camera) is still near 5000 USD, except in some very small on-line shops whose reputation is a bit low.
Not taking into account the actual performance and exact features of each, I would say that Sony will be able to position itself around 2000 USD which is the price point that Canon is setting for all the others. But keep in mind that there is a large body of amateurs enthusiasts that are ready to pay much more than the usual 600-1500 USD price tag for a digital SLR, but the competition is heating to bring Full Frame capability to the masses.
Your guess is as good as mine, but I would say that the tendency is to prepare to a very low price point. 2000 USD will be considered a turning point (notice how Canon is letting the price of the EOS 5D plummet down). A camera willing to position itself as top-quality Full Frame will probably aim at $2500 (I think the price of the Canon EOS 5D MkII or a possible Canon EOS 6D could climb there, not even speaking of a possible Nikon D3x in 2009 with a stratospheric price), but a product aimed at a larger market would have to start around $2000 and preparing for a street price going under this limit (this should be the case of the Nikon D700 -the name is referring more to the D300 than to the D3/D3x pro family- and of the Sony Alpha 900).
