The D3 / D3S killer will soon be announced. Nikon rumors has got the details.
I'm surprised by the 16.2 MP. I was thinking a minimum 18 MP. Anyway, given their recent history, this sensor will produce some mighty clean pics even at high ISOs. The rumored 36 MP beast, the Nikon D800, makes more sense now. Pros will get the D4 because of its superior photo capturing ability and the MP lovin' crowd will get the D800.
The problem? Price. Both cameras will be north of $4,000.
