Nikon responded to the doubts that have been pondering by fellow photographers. Is Nikon D3x's sensor the same sensor as the one in Sony Alpha 900? Is Nikon D3x's sensor manufactured by Nikon or Nikon is still depending on Sony for their digital single lens reflex sensors?

In an article published by Rob Galbraith, Nikon quoted the following:
The Nikon D3X’s 24.5-megapixel FX-format (35.9 x 24.0mm) CMOS sensor was developed expressly for the D3X in accordance with Nikon’s stringent engineering requirements and performance standards, with final production executed by Sony.  Featuring refined low-noise characteristics, 12 and 14 bit output, Live View capability and more, the D3X’s unique sensor design was carefully blueprinted to perform in perfect concert with proprietary Nikon technologies including EXPEED Image Processing and the Scene Recognition System. Meticulous efforts allowed the sensor to become one of the many essential components and technologies which contribute to the D3X’s superior image fidelity.
