A couple of things.
I wonder what people mean by "merging" the 1D and 1Ds lines. The 1D isn't even two years old. I'm not aware of any reason Canon would need to replace that body. So, it makes sense to me that they will continue to sell the 1D for as long as photographers buy it.
I can't see them making an announcement that they are abandoning the line, rather I expect them to simply let it go until the demand no longer justifies making the body. You can still get a Canon EOS-1V film camera from Adorama. We may never see an updated 1D, but I would be surprised if Canon made a formal announcement that they are abandoning the format.
Next, I have a question for those who need more megapixels. Is 32 mp enough? Could this be the worst of both worlds? Too large of files for photojournalists, not enough megapixels for studio shooters? If I'm doing the math right, this scales out to about 12mp in APS-C. That doesn't seem that groundbreaking.
Not criticisms. Not even a strong opinion as this camera is never going to be in my budget. But, just some thoughts.
