Kinect in the movie The Island

There was a scene with contactless fight and XBOX logo all around the place. 
So they use Kinect to entartain clones. 
Then there are so many thoughts. 
Are these factories with clones exist. 
Was NATAL abreviation for "Not Animals, They Are Livestock" relating to the habitants carrying organs?Or something else. Even Microsoft didn't now the meaning.
So Kinect was expensive prototype. Then when technology for motion tracking became affordable they moved it to masses.  
I wished I could see that movie now to write more precisely about it.
