The latest information from the NPS say that environments later this year or likely D3x Nikon Nikon D4 and announced no later than the Nikon Solution in February also will be available. It will be a resolution of 24, x MP in a series of image speed of 5-6 pictures. The new D3 is to replace and not run parallel what astonished me first and also excited.
