It's happening apparently, should you care? Probably not. Current Xbone's will be cheaper and in all honesty they are quite well made, not had any overheating or drive issues with mine.
Come to think of it the only time I bought a "slim" console was with 360 after my launch one red ringed. But, I suppose the cost of making the APU smaller is beneficial for them in the long term and it will use less power no doubt.
I can't wait to see size comparison between the slim and Kinect bar
