We still have no photo of the console itself, but the hardware details are getting more clear. x86 is in, but Intel is out and it's AMD. Single chip CPU/GPU with shared RAM, Blu-Ray, ethernet, wifi, USB, a harddrive etc. Not clear if the camera thing is packed in or will be extra, but they are also talking it up as a pretty standard offering so I imagine it will be packed in with at least one of the bundle options.

Still no price details. Some of the video footage from the game demos looks pretty. Nothing revolutionary, but it at least looks comparable to high end PC graphics now. No announcement if they are going to have support for 4k or UltraHD resolutions that are coming along, but it does at least look pretty powerful compared to last gen systems.
