Well, for the Switch, it was never said every game would be 720p/1080p. Sometimes devs just want to push the system more, or their game may not be optimized well, so they choose to go lower with the res to bump up the graphics/framerate.
The Pro is just a mid-gen upgrade created to make better use of 4K TVs, not pump everything out at 4K. Sony made that clear from the beginning. Even talking about checkerboard rendering and what it does.
Personally, I think the only one who should get flack is MS. They are the ones advertising the X as the "True 4K console," which is actually a lie, since most 3rd party games will probably be very similar to the Pro's resolution and framerate, including using checkerboard rendering.
For the real "True 4K console," you'd probably have to wait til the PS5 comes out. Even then, I doubt Sony will say every game HAS to be 4K. They'll probably allow devs to still use checkerboard rendering if they want to push the visuals even more.
