Valve recently made some major updates to its Steam Controller, and now it appears the device will likely be delayed into 2015. Valve's Eric Hope said that the feedback from playtests is providing a flurry of useful feedback, but taking all that into account and making the necessary improvements will take longer than anticipated.

"We're now using wireless prototype controllers to conduct live playtests, with everyone from industry professionals to die-hard gamers to casual gamers," Hope said (via Polygon). "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."

Valve announced the Steam Controller last year, as part of its push into hardware with Steam Machines and its own SteamOS. The original prototype had touchpads and a touchscreen, but the updated version debuted in March replaced the touchscreen with more a more traditional button layout.
