Oooooooooooooooooo and it gets worse friends. So much bad news it all deserves its own thread.
Engadget.com has an inside-look-video on the development of the Xbox One, watched it and the following line caught my attention:
"We purposefully did not target the highest end graphics. We targeted it more as a broad entertainment play." (at the 5:43-minute-mark)

EDIT: Another interesting tidbit:
"(Microsoft wouldn't give us specifics other than to say, "The system is designed for an SoC up to about 100W, but will vary on the scenario.")" - out of the article to the video from above.
For comparison's sake: this is slightly above the power draw of the current Xbox 360 Slim and PS3 Slim (source).
