Not much info to go off of here, but the French publication Responses Photo published some shots of what might be the Nikon D4. If this is in fact accurate, Nikon's new flagship DSLR could be right around the corner.
Technically, it doesn't exist, but has been recently rumored for a release. As far as specs go, the article merely says that it has an a 16 megapixel FX sensor, 51 point autofocus, 1080p video recording, an ISO range of 100-12,800, weighs 1.34 kilograms and will sell for 5800 Euros. Not sure about you, but I'm definitely excited to see what Nikon has up their sleeve. [Nikon Rumors]
