Xbone does great in the USA but PS4 dominates world wide in sales. IMO I think Sony and Microsoft should've waited another year or so -- I'm not really feeling this graphical leap at all.
I'm more excited to try out the Oculus Rift, and hoping one day VR gaming will reach something close to Sword Heroes Fate or Avatar.
Its funny you mentioned the Oculus Rift. Sony has been working on a VR device to work with the PS4. I believe Naughty Dog is the company that has been using the VR technology to create a game for the PS4. I don't think they released a name for the device yet.
