This forum thread is another example of the reaction Canon photographers have after the Nikon D3 announcement started to sink in.
The fact is, Nikon now has a full frame, high performance camera. Neither of the Canon EOS 1Ds Mark III and EOS 5D are high-performance cameras. The 1D Mark III is not a full-frame camera.
The replies in that thread make for very interesting reading as to what Canonians think Canon must introduce in their next batch of high-end cameras, beginning with Version / Mark II of the 5D body.
