Valve has confirmed that it will be showing off a refined Steam Controller design at GDC 2015 in March, alongside a previously-unannounced SteamVR system.
In November, Valve stated that it would have more to show on the Steam Machine front at GDC 2015 from March 4, and a fresh announcement from the company appears to confirm that.
In a brief statement over on the Steam website, Valve has announced that it will be "giving demos of the refined Steam Controller," as well as "new living room devices" - presumably new Steam Machines.
Intriguingly, the statement also reveals that Valve will be showing off "a previously-unannounced SteamVR hardware system."
The company that produced the popular Steam PC gaming network and the hugely influential Half-Life game series has had trouble finalising its ambitious Steam Machines concept.
Valve's Steam Machines will see a range of tightly packaged living room PCs, produced by a number of established PC assemblers, marketed as a viable alternative to consoles. Each will come with a custom SteamOS for instant couch-based access to gaming content.

Back in May 2014, Valve announced that it had delayed its Steam Machine consoles until 2015. While the concept for the base units and the software was sound, Valve didn't feel it had found the right design and feel for the custom Steam Controller. This is intended to provide a viable replacement for a keyboard and mouse setup in a compact control pad format.
More recently, we appear to have seen the final Steam Controller design leaked in a Steam client beta (see picture).
