Along with a slew of new Steam Machines, Source Engine 2 and VR news, Valve announced an interesting add-on for anyone interested in in-home streaming for their PC games: Steam Link. These $50 boxes (in the US, international pricing is TBD) will stream content from your PC or Steam Machine, as long as they're on the same WiFi network. Adding a Steam Controller will cost an extra $50 when they launch in November, and can handle gaming in 1080p at 60Hz with low latency. Sony's Remote Play game streaming is a couple of generations old, while Microsoft just announced the feature for Windows 10, and now Valve has a cheap hardware solution too. The boxes were listed on the Steam store for a moment (see it in Google's cache here), and pictures showed a slim design, with three USB ports (one up front, two in the back) along with Ethernet, HDMI and power.
