Nikon has more than just a 36-megapixel D800 up its sleeve. The company is also planning to launch a Nikon D4 DSLR to rival the Canon 1DX, and specs of the camera were leaked this past weekend by Nikon Rumors. The camera will reportedly offer 16.2MP, 11fps, ISO 102400 (expandable to 204800), support for the new XQD memory card format in addition to CF, integrated ethernet, 51 AF points, face detection/recognition, and improved video capabilities (e.g. uncompressed video output and buttons for smooth aperture control during recording). The camera may be officially announced early next year alongside the D800.
