I've a feeling that I'm going to be laughing my socks off when the first reviews of the new Nikon cameras come in. So many reviewers blatently biased to Nikon have come up with every reason under the sun as to why the 12 MP count of the D3, D3s and D700 is actually better than a higher MP sensor, will now have to show an extraordinary double think when Nikon release a high MP count sensor.
For a long time Nikon have been behind the curve when it comes to sensors, the D1H only had 2.7MP at a time when Canon 1D had 4.5MP, The 1Ds had 11MP while the D1x was only 6MP. Canon was all Cmos Nikon was CCD, but the proof of the quality is that there are still people using the 1Ds as a serious professional camera, while I've never seen anyone using a D1x because it won't cut it any more. But look back at the reviews, and you'll find the ever present bias towards what now appear obviously inferior Nikon products.
I hope very much that the new Nikon is a good camera, and that it is reviewed objectively and fairly. I hope it is a high MP count sensor, if only to wipe the smug grin of a friend with a D3 who delights in telling me how quickly his (small) files are processed, and how many shots he can get onto one 8GB card!
