Well, that is one way to see it. First, no company forgot about their respective motion control or how you would call it. Sony has incorporated it in the Dual Shock 4 and showed nice tech demos at this E3. Microsoft uses Kinect 2 as a selling point (yeah, not only in context of games, but still). Nintendo keeps a lot of the motion technology alive in its tablet and furthermore didn't forget about their Wiimote. For example in Pikmin 3 it seems to be the preferred input device. So if that was the revolution of the 7th gen, its effects are still lasting.
Is everybody happy with that revolution? Surely not. Most of the time its use in indeed only of gimmickly nature. But in my opinion especially Wii Sports is a good example of motion controls used right. It's a fun game and somehow addictive when played in groups. Not so much when you are playing it alone. The problem in getting real fun out of motion controls considering the HD twins lies in its late adoption. For example there couldn't be any game for PS Move that didn't use motion control gimmickly, simply because all content still had to be accessible for normal PS3 users (which didn't have PS Move). In this context I image Kinect 2 to be used far better than Kinect 1 and fully understand why Microsoft wants it to be mandatory. In the end it all depends on how creative the developers are. Nintendo and in some way the guys that make the tech demos at MS/Sony are quite good at that.
Lastly, what was the real revolution in 7th gen? Most probably motions controls, yeah, but the acquisition of the often mentioned casual market was also a result of a rethinking in game development. Not only Nintendo with its new hardware should be considered as a trigger here, but also the mobile phone market and the rise of indie development and new ways of distribution (Live,PSN,Steam,etc.).
Whatever came with the 7th gen, I would call it a bigger revolution than analog sticks.
