Valve launched the Steam Link SDK and opened the platform for developers. A Kodi port for Steam Link is already in the works.
One of the first things that have been suggested when the Steam Link SDK was released by Valve was a Kodi port and it made sense. Since the Steam Link is a rather powerful device, Kodi is the perfect media hub that can be ported for that architecture. In fact, Kodi already works on ARM devices, so it's a not a big stretch.
