Nvida has used CES 2013 to announce a new console under the name of Project Shield.
Nvidia Project Shield Gaming Console hosts the Nvidia Tegra 4 and includes a 5 Inch Touchscreen that has Retina and 720p Resolution. Apparently the video chip also supports 4k resolutions, making it the first console of its kind to do so.
As for games, "Shield" runs on Android and will play games from Google's Play Store as well as a new NVIDIA TegraZone store.
You will be able to plug this monster into your TV thanks to HDMI out ports etc. Expect to see more on this project very soon.
