Historically a Windows series
It’s going to be a good year for PC Street Fighter fans in 2016. Capcom has announced that in addition to Windows support, they are going to have full Steam capabilities when Street Fighter V launches next year. This includes the Steam Controller, and Steam OS support — so it can run on a Steam Machine without the need to stream.
Also, the beta is now live today on PC and PS4, so have at it! You can actually test out the Steam Controller right now if you want.
