“It is also expected a successor to the Nikon D60 with 12 megapixels and screen viewfinder. So the same sensor technology as the D90. One question that arises is what such a camera should be named. D60-successor can not be called D70 or D80…”
Here is also another link to a online store in Australia that promises Nikon D3x to be in stock by December 31, 2008.
