There has been a great deal made of a (faked) Nikon roadmap that outlines the releases of camera and lenses through 2010.

Some of the details include:

Nikon D4
15.7MP (more sensitive and with less noise)
Up to 16fps with “double exposure”
ISO 200-12800 (plus extended range)
61-point AF
1080p video at 30fps
CLS control (although no flash is mentioned)

Nikon D4x
30.2MP
ISO 100 – 6400
6fps
1080p video at 30fps

What I find amazing is that every camera has video.

Do you want video? I don’t. Just give me a camera with great ISO capability and a rugged solid build.
