Get kids, it works too. They can even retrieve the controller for you. Kinect, your move :)

There's also 3DS, which like I said had gyroscope but used in a very timely, almost non-existent way. 3DS and WiiU are the both systems I was alluding to (eight generation), which Nintendo almost entirely glossed over motion controls.

Also, Wiimotes as a primary controller for the WiiU is...not a good example by any stretch of the imagination. First of all because the system's primary controller is the Gamepad (you need the Gamepad for most things WiiU related, not to mention that not every WiiU game supported Wiimotes but all do support the gamepad) and I think this is basically something that can't be argued against, and second of all, because most of the games that did use the Wiimote as an auxiliar method for the gameplay did it without recurring to motion controls, but basically using the Wiimote as another standard controller, such as the case with New Super Mario Bos U or Smash Bros. 

WiiU gamepad does have motion controls, but like I replied to d21lewis, it only have very few examples like Splatoon, Zelda and probably something else I can't think of for its use. Motion controls on WiiU were barely non-existant, and hardly ever used at all. It wasn't a "core" feature of the system because it was barely utilized, it was just something extra implemented as a built-in. If Gamepad is somehow valid, so are the Dualshock 3 (EDIT: not necessarily, since it was only a specific sixasis model, but still) and 4 then, which also used motion controls and thus void your notion that it is "non-existent" in other systems.

hopefully one day! :P

Yeah, I just went and double checked because after I'd written that I seemed to remember reading an article on it. They're 'promote' it more then. They're blurring the line. Games are not now made for the XB consoles, they're made for the PC and then tweaked to run on the XB. This is why we are very unlikely to ever see an XB1 exclusive ever again. 

Remember that last year MS started pushing Kinect deals even though they'd released an update for Kinect that removed the motion control software.

And now all those people who bought Kinect because of those deals, got home and updated Kinect only to find motion control no longer worked, now find that the Kinect has been discontinued and will no longer get supported. MS will always be MS. 

I can't reply to you until tomorrow. Family time.

What about Nintendo selling 2DS consoles and pushing them knowing damn well the thing will be DOA in a year? Or Sony selling PS2's in 2010, even though they had absolutely no intention of developing AAA games for it anymore?

All three companies do this. It's not exclusive to Microsoft.
