The latest rumors suggests that Nikon will reduce the price of the D800/D800E DSLR cameras in the US on December 15th, 2012. I am not talking about an instant saving when you buy a body and a lens, but a direct price drop - just like the D600. I was told that Nikon is making this move in order to match the recent $200 instant rebate on the Canon 5D Mark III. I expect the D800/D800E price drop to be also $200.
Update: the price of the Canon 5D Mark III now dropped to $2,999.
