What I don't get is, with the 1D X brand being marketed as "highest quality ISO, fast shooting speeds, lower pixel count, best video" the split mentioned here (of course it's a CR1) has the 1D X like camera getting a 5D III moniker, while the slower-shooting, high MP camera gets the X name...it seems inconsistent to me.
Something tells me this might just be an attempt to put names to two prototypes out there in the field, and nothing to do with the names we'll end up seeing in shipping units.
