Which is what makes the whole thing really fucking confusing. Since the XOne is so much lower powered.
The only thing I can guess is Microsoft and Sony are using different metrics on what "Break Even" means... with MS including more.
Either that or Kinect is way more expensive then we can imagine.
I believe the new Kinect has dedicated chips which has to up the costs on top of the advanced specs in the device itself. Then theres the fact that yields on the main SoC are likely to be relatively low compared to the PS4 chip by virtue of being a much larger chip.
