As has been stated frequently before on these forums, especially by Neuro, the sensor is often one of the least important features for many types of photography.
I am not sure what Neuro actually said, but the fact is that the sensor size (not necessarily mp count or DR, or noise) is one of the most important factors in many types of photography, excluding macro and telephoto. To be more precise, it is one of the most important factors when you care, but then the same applies to lens choices, smartphone cameras vs. more serious ones, MF/LF vs. 35mm, etc.
Sure, of course the converse is true (I never stated otherwise). My point is that the fact that the 6D has a larger sensor than the 7D II will likely have does not intrinsically put it at a higher or lower ranking on any hypothetical scale. They are different tools for different jobs. For those who need a FF sensor because it IS the most important factor, the 6D and 5D III offer excellent options. For those who need an APS-C sensor in a camera with high FPS and excellent AF, the 7D II would, for them, be the better choice than the 6D for sure, and in some cases even better than the 5D III, and certainly a far more accessible option than the 1D X (even at a price point of $2500!)
I'm just trying to debunk the notion that the 6D, simply because of its model number and sensor size, therefor must be better or higher ranked or more professional than the 7D line. I would put the two at an equal level or tier of professional grade DSLR equipment, designed for different use cases and photography types, with feature sets to match.
