To be honest, most of these "innovations" like the DS with its touch screen, EyeToy/Move/Kinect/WiiMote, ... these technologies were trying to innovate, but these input devices were simply inferior to a standard controller.
You have tight controls with a control pad and it does its job. There is almost no room to further improve... to be honest, the controller were never my problem since the NES days. They have become a problem because companies tried to fix something that never really was broken. They got blinded by the Wii success (because the fitness games had a few very strong years), but ultimaley none of these control devices really had a lasting impact....
3D was pushed and it seems that most people simply do not care about it. I think that VR is the next thing that will be pushed but will ultimately be neglected by most of the gamer and developers after a few years.
The one thing that needs really new ideas are the games. I got the feeling that in the last few years the genres were narrowed down and that most games tried to be the next CoD. There was more diversity in the last generations...
