That "subject tracking" they are referring to, doesn't that require that you enable all the focus points, and let the camera chose focus? Do anybody on these forums know anyone that shoot their 1DX in full auto mode, and let the camera choose where to focus? I guess most pros want to be in control of that. It seems typical DPreview to test out and mess on with a house wife feature (I'm not trying to be sexist here), in a top level pro camera.
Yes, all points enabled with you selecting the starting point. But you know what? If it works, why would anyone NOT want to use it - it's not a "house wife" feature if it works and makes your life simpler and faster.
This is something Nikon's implementation is really good at - you can leave the starting point at the center, hit an eye with it, recompose, and it will follow *just* the eye really well with the active focus point. That's handy and quick and it's silly to poopoo it. iTR will usually end up keeping on the face, but will have 5 active focus points over the nose eye and cheek if you do the same, and thus miss focus if you are close to your subject.
