The design for Valve Corporation’s unique touchpad game controller has been finalized with more details coming at the Game Developers Conference in March, says Origin PC CEO Kevin Wasielewski.

“At GDC, they’re going to have more information, and we’ll be there.” Wasielewski said. “That’s the official stuff we can say. They came out with the controller, then they got some user feedback, and they had to revamp it; they got some more user feedback and had to revamp it again. So they went through that like three or four times. And now their controller is finalized. So now they’re going to production and at GDC is when they’re going to announce more stuff.”

Wasielewski’s words and other statements made by Valve have led to speculation that the long-awaited Steam Machine console will officially launch at GDC 2015 in March.

Valve told Gamasutra earlier this week that there would be no Steam Dev Days conference this year. “This year our focus will be a bit different, so we are planning a larger than usual presence at GDC,” a Valve representative said.

Original concept of Steam Machines “pretty much dead”

Wasielewski also spoke about the Steam Machine system itself, saying that he believed the term was no longer accurate.

“I think that’s kind of pretty much dead,” Wasielewski said. “It’s like a living room PC–is now the new term. Living room PCs have been around forever. That’s not anything new either. But it seems like there’s a legitimate demand and push for living room PCs.”

There has been fan speculation surrounding a home console developed by Valve for years, with fans originally dubbing the idea the “Steam Box.” But the concept of the system has shifted away from the idea of a home console that would compete with Xbox, PlayStation or Nintendo.

Instead, the system will be more like a living room media PC with Steam game functionality.

The Steam Machine is not an individual product but rather a type of system that can be made with different hardware specs by different companies. Users will even be able to make their own version of a Steam Machine using Valve’s free Linux-based SteamOS.
