Nikon should upgrade its full pro DSLR with the D3s in less than a month based on clues left by itself and outsiders. A French copy of the company's itinerary (PDF) for the Paris Expo on October 15th refers to the launch of a "nouveau reflex Expert produit Nikon," or a new pro DSLR product. The date coincides with reports of a D3s appearing at the same date and is unlikely to be a recap of the semi-pro D300s and amateur D3000.
