We have new Wii Fit, Mario & Sonic, rebooted Wii Sports, Kinect Sports, Wii Party this gen though. All these games were sales dud's in terms of massive drop-offs from last gen. Nintendo Land also had extensive use of the motion controller and that couldn't carry the Wii U for even a couple of months.
That's indicative of a fad, they should have solid sales across the board if there was a huge demand for these types of games. Just like Guitar Hero today is going to sell nowhere near the peak Guitar Hero games. Fad's come and go.
That's not at all like not getting a new 2D Mario for two generations.
There's no market need for waggle games, the appeal in the first place was that it allowed people who couldn't play games to join in and play, but now iOS/Google Play had thousands of free dumbed down experiences for that crowd available anywhere. So that market need is taken care of.
Leaving waggle gaming exposed for the shallow experience it always was. Attempts to make "deeper games" with the concept really don't fly either because it's just not well suited for long play sessions. There's really not a huge groundswell of support to include motion controls in the new Zelda for example, because most core gamers are happy to play without it.
