As for the GPU, I think you are wrong here. An AMD 7770 GPU (80 Watts) has about 3 times the shader count (640, 160*4 vs 240, 48*5) as the Xbox chip and runs at twice the clock, so it is around 6 times faster than what XBox360/PS3 have. That is more than enough power for 1080p/60Hz. Add a refresh and toss out all the PC stuff consoles don't need and you have a powerful GPU that runs less than 60 Watts.

AMD 8core architecture is actually ideally suited for stuff like Kinect2, so expect to see 1 (2cores) or even 2 (4cores if camera resolution is very high) groups reserved to Kinect2. Of course, not using Kinect2, hence freeing all cores, will give the XBoxNext enourmous power.

As far as I've seen, the HD 7770 is rated at 100W, and it doesn't give the performance of a GTX570 (the rumor talked adout dev kits featuring the 8 core Intel CPU and a GTX570). To get that level of performace you'll need a HD7850 or 7870, and those cards use 120 - 150W. Even with Sea Islands, the HD8xxx series, you'll need an HD8770 to get that performance level, and you'll still be in the 100W mark.

And then you not only have to worry about the power but also about other things as well. The Sea Islands GPUs are stated for release in spring 2013. If Microsoft launches their console in 2013 they will be in the hands of TSMC and as Nvidia and AMD know way too well, they aren't that reliable. They could end with a console launch without enough chips to met the demand and the ones they have costing more than planned.
