Valve postpones Steam Machines to 2015 because of controller

We’ve been getting emails from the Steam community asking us how our in-development Steam Machines are coming along. We’re now using wireless prototype controllers to conduct live playtests, with everyone from industry professionals to die-hard gamers to casual gamers. It’s generating a ton of useful feedback, and it means we’ll be able to make the controller a lot better. Of course, it’s also keeping us pretty busy making all those improvements. Realistically, we’re now looking at a release window of 2015, not 2014.
