Wii U has gamepad, motion controller gaming, free online
PS4 advantages is better graphics, better frame rate, cheaper online, more games and better Playstation PLUS games.
What are Xbox One advantages? Kinect was but because Microsoft dropped this, now we have no Kinect games. Games with Gold costs more than PlaystationPlus and has weaker games. What are fair Xbox One advantages over Wii U and PS4?
MS never dropped Kinect they're just letting you buy it separately if you want there will still be Kinect games if that's what you want.
MS will be providing better customer service because they know they're behind and try and screw the consumer less hence the whole Titian Fall bundle. Why do you care anyway Hermit?
