The Nikon D4 DSLR
I think it's a given now that we won't be seeing a Nikon D700 update for 2010. Call it an educated guess, my opinion, intuition... whatever, but I'd be willing to bet on it.
The good news is... strike that... the GREAT news is that I think we'll see a high megapixel Nikon D700x ( D800 ) in 2011. With the Nikon D4x anticipated in 2011, Nikon should have no problem letting the D700x /D800 have the existing Nikon D3x 24 megapixel sensor.
Now that's a camera a LOT of people are going to want, myself included! A D700 body with the D3x sensor will be a hot seller. I anticipate Nikon having a hard time keeping these in stock in the early days of the roll-out.
Here's how I see the Nikon 2011 Pro Level DSLR Line-Up...
Nikon D700s - Brings the INCREDIBLE Nikon D3s sensor to the super popular Nikon D700 making it capable of seeing in the dark, just like it's big brother. Will also have full 1080p HD video with full manual controls and an external mic input.
Nikon D700x /D800 - Brings the SUPER RESOLUTION D3x sensor to party in a Nikon D700 body. For those that need HIGH resolution, but can't afford the expense of a D4x or don't like the bigger, heavier bodies, this is your camera. May have 1080p HD video, may not. Let's hope it does.
Nikon D4 - Brings a new 16 megapixel sensor to the party, capable of the same SUPERB high ISO of the D3s sensor, maybe even a stop better. Will also have full 1080p HD video with full manual controls and an external mic input. May also have video RAW settings.
Nikon D4x - Brings a new 38 megapixel sensor to the party, putting Nikon back in the lead for highest megapixel sensor available in a DSLR. If you need MAXIMUM resolution, this is your camera. Medium format companies cry like babies when the D4x is officially announced, and plot to sabotage the production facility. May have 1080p HD video, may not. Let's hope it does.
May also have video RAW settings.
