This is where you have to be careful about generational and console delineations. Again, power is not the criterion. The Xbox One X doesn't differentiate itself enough from the standard model to gain acceptance as a separate and independent console.
Admittedly, these rules aren't written in stone and their application is largely centered around industry consensus. With that in mind, the industry still qualifies the One and One X as the same console....just different models.
Which funny since the gap between the normal and the X will be bigger when comparing the gap from the X with the next generation ( most likely )
Funny indeed and likely a first for any mid-gen model upgrade against the original model and next gen successor. Interesting times.
