As a 1DsIII user, the 1Dx isn't the upgrade I was looking for. My next body will be a 5D3 or D800, so the specs of those two bodies are all that I care about. The 5D3 probably won't be released until after the 1Dx, so that's the only reason I care about when the latter hits the market.To be sure, it wasn't the camera I was looking for either. I think combining the 1D line was a huge mistake. I mean, isn't one of the main reasons they kept the camera at 18MP was to be able to shoot so quickly? Wouldn't a lot of studio photographers been a lot happier if they could have shot at half the speed but with much bigger images?
I hate it when somebody tells me "you don't need anything more than 18MP." I have heard that a lot. How do they know what I need? When working with a model, I certainly need 27MP much more than double digit frames per second. I was kind of hoping the new 1D would rival medium format. When I'm shooting sports I don't want full frame. It's an impressive camera, but I really think they only people it's perfect for would be like National Geographic photographers and certain kinds of sports on smaller fields/courts. It's just the wrong camera for me and a lot of others, as well, even though it has a lot of really sexy features.
