Part of the issue is that Canon forces those who need a high megapixel sensor and great autofocusing to choose between the 7D (a crop camera), the 1D Mark IV (much more expensive than the 5D Mark II and another crop camera) and the 1Ds Mark III (ridiculously overpriced, given its age).
Is it any better elsewhere? The D3x is the only choice for a "high MP" Nikon body, and it's 8k.
People who need "high MP" and "fast AF" are shooting on the very forefront of camera technology, and it is not unreasonable to expect that they need to pay a substantial premium for that ability. People who don't "need" it but want it, should also be expected to pay up for the luxury.
Simply put, seems as if everyone wants an ultra high MP camera with ultra fast AF but don't want to pay the ultra high price.
