Gamers will have until 2015 for Valve's console launch.
According to BBC News, the interactive entertainment game maker reportedly needs more time to develop the machine's two haptic-feedback trackpad controllers.
"We're now using wireless prototype controllers to conduct live playtests, with everyone from industry professionals to die-hard gamers to casual gamers," the company said in a statement on their website. "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."
Valve officials said they are anxious to release the system to consumers, but want to make sure they have the best product to offer the public.
"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," the company said in the statement on their website. "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."
The change could affect other businesses that intended to sell their individual versions of the system upon Valve's initial Jan. 6 unveiling date.
"The first generation Steam Machine offers something for every gamer, which is a critical part of extending Steam into the living room," Gabe Newell, Valve's co-founder and managing director of video game development said in a statement at the time. "With over 3,000 games and more than 65 million gamers on Steam, it's important to offer gamers a variety of Steam Machines that allow them to select what makes the most sense for them."
A gaming analyst at consulting service Ovum said the machine's SteamOS-operated controller is a vital part for using the equipment.
"It is targeting a very demanding demographic with the Steam Machine platform, and the controller is one of the key features designed to address the impression that PC gaming can be slightly inaccessible," Ed Barton stated. "It's a very ambitious concept to try to replicate the accuracy of a mouse input with the controller's two circular touchpads - and if it doesn't work, the platform would likely struggle to get off the ground."
