SHOW ME YA MOVES!
I have high doubts about the Wii U outselling the competition like its predecessor did with flying colors. For one, the Wii U is a Gen VIII console, meaning, it is trying to compete with competitors. This means that the PS4 and Next Xbox will outclass it as far as sheer power goes.
Why does this mean anything? The Wii was substantially less powerful than its competition and it still sold oodles more.
The next problem I have is that the Wii U has some of the 3rd party support that the PS3 and 360 had, and the majority slew of games released on PS3/360 were lacklustre, or decent at best. This could plague the Wii U just as much as it did the PS3/360 and ultimately put the competition ahead.
You act as if Nintendo won't release plenty of stellar 1st party titles like they did with the Wii.
One other thing is that the Wii U, being established as at least above PS3/360 par, lacks any form of media device. We cannot play DVDs, CDs, Blu Rays...anything at all. Surely the PS4 will take after the PS3 and become a world class multimedia device. The 360 had some multimedia capabilities, why wouldn't the nextbox take advantage of this as well? Ultimately customers may decide that they're getting more bang for their buck with the competition.
Actually, the Wii U has a little thing called Nintendo TVii.

Needless to say, I think your fears are unfounded.
