Valve has delayed the launch of its first pieces of hardware, pushing the release window of its Steam Machines and Steam controller from 2014 to 2015. Valve's Eric Hope said that the release dates were pushed back to allow the company to work on the controller, after live playtests with wireless prototypes generated a "ton of useful feedback." While Hope said that feedback means Valve will be able to make its Steam controller "a lot better," it's also keeping the team behind the project "pretty busy making all those improvements."

"Realistically, we're now looking at a release window of 2015, not 2014, ' Hope said.

Hope didn't clarify how the delay will impact the planned launch of its Linux-based operating system, SteamOS.

Valve's Steam controller sports two touchpads on its front, in place the analog sticks present on most modern console controllers.
