I don't think so, everyone is just making silly jokes like "Wii U haz more gmaez that run at 60 frames than Xbone and PS4", yet they don't consider other factors, like the fact that those two consoles are more powerful than Wii U, so obviously they are jokes, it's people just trolling and making fun of the situation. 

"Why is it that the Wii U can handle a solid 60fps but the PS4 and Xbox One can't?"

2nd comment. Ignorant at best, trolling at worst.

And how is that making shots at Microsoft and Sony? They are just trolling/making fun, dude; this is what happens when comments without any kind of substance are taken too seriously: a regular console wars discussion is started in a technical analysis of a Toad game. That's really not necessary, we know that Xbox One and PS4 are more powerful than the Wii U, so why do we bother trying to figure out why the "Why is it that the Wii U can handle a solid 60fps but the PS4 and Xbox One can't?" comment is so pointless?

Did you intend to answer your question with the following sentence......

But it's still not serious, not enough to dedicate 10 pages of discussion of this topic. 

I've written papers for university that were longer and less serious. :D

Interesting note: in some levels the gamepad screen decouples from the main screen while still maintaining 60fps.

The gamepad renders at 854x480 (409,920 pixels) which when added to the main screen (1280x720, or 921,600 pixels) gives us a total of 1,331,520 pixels, which is just shy of 900p/60fps.
