ok in Valve's ever expanding world of video games they have decided to toy around with the idea of a home console for your living room with all the power and precision of a full custom PC and the versatility of the console. as the artical im linking at the end of the post says the official specs for the prototype has a full size GTX titan and an intel processor (which i am assuming to be one of the i series quad cores but could still be one of their lower modles) the controller as it stands has no analog capabillity, it is all done with two hyper sensitive touch pads that can be configured to each user's personal senstivity prefrances, as well as custom mapping of roughly 10 other buttons. one model even stated having a touch screen in the center to allow for all the key mapping that would be preasant if you were actually using a standard keyboard. possibly even virtual macro for the virtual key maps. it is still in development and prototype stages but is predicted to be avalible to beta testers in 2014.
