Unofficial expectations of a Nikon D90 replacement were fueled today by early word that Nikon is prepping retail for the new model. Multiple reports have come in of returns or delays for the camera and accessories in its class. One retailer talking to Nikon Rumors said all D90 demo units were being returned, while another with backorders for the SB-600 flash was told a replacement is expected by the Photokina shown on September 21.
