Nikon Rumors have posted what they claim are the specifications for Nikon's next range-topper. The D4 seems likely to go head-to-head with Canon's recently announced 1D X.

Here's the spec list:

• 16.2 MP
• 11 fps
• 100-102,400 native ISO range, expandable to 50 and 204,800
• CF + XQD memory card slots! That's right, the Nikon D4 will have the new Compact Flash XQD memory card slot.
• Compatible with the new Nikon WT-5 wireless transmitter
• Integrated Ethernet in the camera
• Face detection/recognition function that will be working in the viewfinder
• Improved video
• Uncompressed video out through the HDMI port
• Ability to assign the two buttons on the front of the camera to smooth aperture control during video recording
• Improved 51 AF points
• AF detection range will go down to EV-2.0
• Autofocus system: 9 cross-type sensors that are operational up to f/8

Interesting if true.

By comparison, here are the announced 1D X specs:

• Full Frame
• 18.1MP
• Dual DIGIC 5+ – 17 Times The Processing Power of DIGIC 4
• ISO 100-51200 Native
• 100,000 Pixel RGB Metering Sensor
• EOS iSA (Intelligent Subject Analysis)
• 61 Point AF
• 21 f/5.6 Cross Type Sensors
• 20 f/4 Cross Type Sensors
• 5 f/2.8 Cross Type Senors
• EOS iTR AF (Intelligent Tracking & Recognition Auto Focus)
• 12 Frames Per Second
• 14 Frames Per Second JPG Only
• 400,000 Shot Rated Shutter
• Ethernet Connection
• March Availability

So based on this, the D4 will be slightly lower resolution than the 1D X, but with a higher specified ISO -- but is that enough to fight off the competition?

I think that this leak makes sense, especially in light of the rumoured D800 specifications. It would appear Nikon are pursuing a strategy of differentiating the higher end bodies by high sensitivity/low resolution, and lower sensitivity/high resolution.
