Dont think Sony is behind. Sony sensors are being adopted by Nikon and are going to exmor sensors. Kodak is a cheap camera, but tell me why Hasselblad is using their 50megapixel sensor for their highest end camera!
According to German photo magazine, Foto Magazin, the future Nikon D3x pro SLR camera will be fitted with the Sony image sensor that was presented a few months ago and that is expected to appear on the Sony Alpha 900 camera (high-end D-SLR from Sony). If this is confirmed, it would mean that the Nikon D3 will have a successor under the name of Nikon D3X (or D4) and that the Sony sensor is really of the utmost quality.
We knew that it was coming with 25 million pixels, but it could have been short on quality compared to the D3 (or D700) sensor because of its small (but many) pixels. For Nikon to accept to use this Sony sensor (and not a better one) at this level of products, they must be sure to have the best possible silicon piece: Pros want wonderful images, not only big figures (a big bunch of pixels).
