It looks like the new Nikon D4 may arrive just prior to CES/PMA 2012.
If Nikon Rumors turns out to be right with the latest rumor, then the D4 could also be shipping prior to the end of January 2012 ahead of the Canon 1D X’s delivery date of March 2012. As a recap, the Nikon D4 is rumored to be an FX format camera with a 16.2MP image sensor and will use the new XQD memory card format.
Other rumored specs include a sensitivity range of ISO 50-204,800 (with expansion), 11 fps frame rate, and uncompressed video out via HDMI. Christmas may be running a little late for you Nikonians, but it sure is starting to sound good.
Nikon D4 ISO range will be 100-12800:

Right. But with expansion settings the rumors say 50-204,800.
Can you tell me when Nikon will release the D400. It was mentioned back in July. The d4 and d800 will be arriving early next year.
