PAOerfulone's prediction on how future of Wii U and how NX will shape up.

[PAOerfulone]

So if NX turns out to be less powerful than PS4 and XBO, than that WON'T make matters worse? As much as we'd like for graphics not to be an important factor, it is. That's just the gaming world that we live in. The first question people will ask when a new console is revealed with a launch library is almost always, "How are the graphics?" Rather than, "How does the game play?" Just the way it is, sadly.

Also, part of the reason why third party games were so low for the Wii U, was because on top of being technically and graphically inferior to its competitors, had a gimmick that most third party companies didn't want to develop for because it drove up development costs big time, if there was no GamePad, and the main controller was the Pro Controller, we would've seen a lot more third parties games with effort put into them. Even if those ports were coming from PS4 and Xbox One, because even though the Wii U is graphically inferior, it's not THAT graphically inferior compared to the Wii vs the PS3 or 360.
This is why I also mentioned the concept that Nintendo is planning with NX to also be a key variable to how well the system does whenever it launches.
