Nobody in the industry gave motion control a real chance.

They'll still be a gimmick in the future.

Fingers are our best and most responsive tools, which rely on haptic feedback to work at their best. No motion control device can replace buttons and analog sticks when it comes to timing and precision. Well apart from the mouse, that's a motion controller too. However gesture recognition never caught on with the mouse, why should it with a wand you wave in the air?

It's fun as an add on and they are much better for games that rely on arm and wrist movements as input: dance and sports games. The industry is giving those plenty of chances.
I wouldn't mind seeing another puzzle game like Tumble, Zack and Wiki or a full fledged adventure like Datura. Plus pixeljunk 4am is a personal favorite, too niche though.

For other games it's just not reliable and accurate enough. I didn't like it much in Skyward sword. It only correctly recognized movements 80% of the time, forward thrusts even less. Not ideal and not worth losing camera control over. The bomb tossing/bowling was well done, but gimmick. Imagine playing Dark souls 2 with a control scheme that inherently has more lag and sometimes doesn't respond or does the opposite. No thanks.

And as fun as dance and sport games can be during the day, at night I prefer to recline on the couch, sit in the dark, and play without having to talk or worry about remaining in sight or correctly calibrated or whatever.

It's the future for sports and dance games, and the future is already here.
