This is a revised estimation on my part of the cost of Wii U. $150 for the tech under the hood, $50 for the "privilege of being able to play Nintendo Games," and $100 for the Gamepad.
I still say you get $300 to $350 ( maybe as high as $375 but doubtful ) worth of tech under the hood of Xbox One, and $400 to $450 worth of tech under the hood of PS4.
