As with the last few designs, the most recent appearance of the Steam Controller has been unearthed from files contained within the latest Steam Client Beta update. The new design, shown below, appears largely similar to the previous iteration and features an analogue stick, four main buttons, and two touch pads. The most striking change from previous designs is the appearance of a four-point directional guide on the left touch pad. It's not entirely clear just yet how the four-point guide will be used or what it's main purpose is, but we'd imagine the left pad may now be re-configurable to feature as a softer, more diverse alternative to the standard D-Pad by offering more directional input than just the standard four-points of motion. While it has yet to be officially revealed by Valve, it's extremely likely this new design will be shown off in public for the first time at GDC 2015, as Valve's Doug Lombardi recently confirmed the company would have a "large Steam Machine presence" at the event in March.
