Many people use and love the gaming software Steam and it is a well known fact that Valve, the people behind Steam and several amazing games, are working on so-called Steam Boxes. These are supposed to be basically gaming PCs that come with Steam OS, a customized version of Debian Linux, all ready for gaming on Steam.
These devices have raised all sorts of hype, and the official release has been pushed back into 2015, as outlined in a post on a Steam Community post.
This is mainly by yet another re-design of the controller, this time making it wireless. Because of all of the testing they are putting these devices through, lots of bugs and improvements are surfacing, leading to an extended development period. Thus, AXIOM (author of the post and a member of the Valve team), says
Realistically, we’re now looking at a release window of 2015, not 2014.
While this seems kind of ho-hum now, I think it will all work out for the better, leading to a better final product.
