I just posted about the latest Sony a500 and a550 leaks @ PhotoRumors.com. The sensor in those rumored cameras may give us some hints about future Nikon DSLR models. This was the case with the Sony a900 and the Nikon D3x: after Sony released the new sensor, Nikon followed with its own (better) version (Nikon sensors are “made by Sony, designed by Nikon“).
