I think Kinect is more evolutionary than revolutionary -although it can be unique in its own way, and maybe revolutionary with the likes of Occulus Rift- as it began as a project when the Wii and motion controls were at their peak.Probably we've gone long enough to say there's not much revolutionary really going to come with Kinect.
That said in this connected age, including a voice recognition mic system and a video camera with every console is alone probably a decent idea, regardless of any motion control, provided eventually the added cost of it becomes low.
The fact that it wasn't bundled with every single X360 was its main handicap but there were a few games, especially a survival horror from Sega, which shown the great amount of potential it can have.
If it can provide voice and gesture controls satisfactorily while sitting, you could use your hand to grab and move characters around the screen (think about a platformer with those options) or it is used smartly in mystery/adventure games or featuring some shoehorned controls like in BF4, then it can have the success it deserves.
