The Xbox One has a potential fatal flaw and Microsoft knows all about it.
My opinion on the matter and how to solve it is for Microsoft to not make the Kinect necessary for the console to function. There has to be secondary controls on the Xbox One for those who do not want to use the hands free features or talk to the Kinect. So perhaps Microsoft knows this and is just pushing the Kinect's new features in an attempt to gain popularity for an accessory that certainly did not meet expectations on the Xbox 360.
This issue with the new Kinect is just one of the reasons many people were disappointed with Microsoft's press conference leaving gamers with so many more questions than answers, hopefully Microsoft can write their wrongs in June at E3.
