Valve announces a delay to the launch of Steam Machines, the SteamOS-powered gaming boxes, saying they are now anticipating launching these in 2015, rather than sometime this year, implying that tuning the Steam Controller is the issue. Here's the post from the Steam Universe group (thanks Ars Technica) announcing how Valve Time has struck once more:

We've been getting emails from the Steam community asking us how our in-development Steam Machines are coming along. It's great that you're excited about it, and we know you appreciate it when we keep you in the loop on stuff like this, so we wanted to give you all a quick update.

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.

Obviously we're just as eager as you are to get a Steam Machine in your hands. But our number one priority is making sure that when you do, you'll be getting the best gaming experience possible. We hope you'll be patient with us while we get there. Until then, we’ll continue to post updates as we have more stories to share.

As always, we love getting feedback on the Steam Machine and Steam controller from the community. After all, you're the people we want to be happiest when we release them.
