I wouldn't be shocked. The Pro feels a little unnecessary.
PS4 Pro is a bump up from PS4, but I feel the same too.
PS4 Pro is a system that came out 3 years after PS4, yet it's only real difference is a bump in visuals and 4k streaming. Same controller, bigger footprint, heavier.
On the other hand, MS' 3 year upgrade was an X1 redesign: X1 S added a 4k drive, smaller form factor, internal brick, better controller, IR blaster, slightly improves game visuals (by far not to the extend of PS4 Pro... more like improved and stable frame rates), and probably some more tweaks.
Scorpio (which is a real upgrade over X1 S) bumps up specs leading to better visuals, but also adds a ton of new features, a 4k drive etc....
PS4 Pro is a car maker's model in year 4 of 5. If you compare the year 4 car to the launch model, year 4's car improves on everything from year 1, but it's still kind of the same car. You get a better engine, but everything else isn't that much different.
X1 S is like year 2 of a 5 year car platform. Year 2 tweaks a bunch of aesthetics, but the performance and engine are basically the same as last year.
Scorpio is a car maker's relaunch of a brand. Everything is new.... looks, interiors, engine, features.
