Kinect is an accessory that could be removed from the Xbox One bundle and the console would run fine. Whereas Blu Ray was a piece of hardware necessary for the PS3 to run. It doesn't matter how beneficial Blu Ray was. Blu Ray, like cell architecture and other hardware components (which arguably were not beneficial), together form the PS3. Kinect is not a component of the Xbox One and does not form the Xbox One. It's a seperate entity sold with the Xbox One.
Further, in Microsoft's case, the "unnecessary" accessory could have been removed much easier. Microsoft can reasonably sell the two as seperate products without any hassle. However, if Sony sold Blu Ray as a seperate product, the PS3 would not function.
