The company has yet to announce a release date for SteamOS. It is said that this could be the operating system behind the rumored Steam Box computer. On Steam's website, they have hinted towards other announcements coming within the next few days. They currently have a teaser page with 3 icons that represent 3 different announcements for the living room — SteamOS being the first one.
"When it comes to gaming, SteamOS will work particularly well for audio performances and reducing input latency. Yet, only Linux games will work on SteamOS. While many games are now available on Linux, it still has a long way to go compared to Mac OS and especially Windows. That’s why you will be able to run Steam on your Windows or Mac computers in another room and then stream your games to your living room using SteamOS. Latency shouldn’t be an issue, as everything happens on your local network."
The Steam Operating System will work much like your Xbox. Everyone in your family will be able to create a seperate profile, watch movies, browse music and play the same games with the family sharing feature.
Valve has not announced a content partner but did say they were “working with many of the media services you know and love.” Services such as Netflix, Amazon Instant Video, Hulu Plus and HBO Go should make their way to the platform.
While many of these services are only available in a few countries, SteamOS will be available for everyone in the world. We just don’t know when or what devices will run SteamOS. The second announcement is set for Wednesday, September 25th.
