The time has come! We are ready to begin shipping Steam Machines and Steam Controllers to the 300 selected beta participants. The machines are due to leave the factory on Friday!
The 300 selected beta testers are being notified today (at about 2:00 p.m. Pacific Time) that theyll soon receive Steam hardware and SteamOS for testing. Each selected user is also being awarded a special badge on their Steam Community profile, indicating that theyre a beta participant. In addition, a number of games that run natively on SteamOS are being added to each selected users library.
Weve had to make the difficult decision to limit our beta to the U.S. only, because of regulatory hurdles. This was not our original plan, and it means we cant collect beta feedback from Steam customers world-wide, which is pretty unfortunate. All things considered, were sure it was the right decision, because the alternative was to delay the whole beta beyond the point when wed be able to incorporate any feedback into the 2014 products. This decision only affects Valves 300 prototype units; the commercial versions of Steam Machines that are for sale in 2014 wont be affected by this. More information on those will be announced at CES on January 6.
SteamOS will be made available when the prototype hardware ships. It will be downloadable by individual users and commercial OEMs. (But unless youre an intrepid Linux hacker already, were going to recommend that you wait until later in 2014 to try it out.) Well post info soon about that. Oh, and stay tuned for the in-home streaming beta to begin soon, too!
Happy holidays. And happy unboxing to our beta testers. See you on Steam.
