The high MP camera: how many people here would buy one today if Canon made essentially a D800 at D800 price (assume 5D style body)? And how many here would buy a 1D body version of that camera (assume more fps and 1D X AF) at 1D style price? To me, 1D = unnecessary bulk and cost.
I would buy the camera if it comes in a 5D style body. I have always hated the big 1D bodies, and I really don't need the extra size / bulk for my studio work or my landscaping / travel photography.
But then again, I won't buy the camera at all, if it can't beat or at least match
the DR performance of the D800.
I am pretty sure that Canon will once again ultra-fail when it comes to low ISO read noise, and it would not surprise me if the new camera has vertical banding too, just like the 5D3.
Canon will eventually catch up with Nikon's (Sony's) sensor tech, but it won't happen this year or the next.
