Street Fighter V has been confirmed via the following trailer (that has since been taken down from YouTube), and by the looks of it it's heading "exclusively" to PS4 and PC.
Presumably the trailer in question leaked ahead of tomorrow night's PlayStation Experience event in Las Vegas, which would make sense if it's an exclusive announcement. If this proves to be accurate, and it certainly looks like it's correct, this is a huge coup for Sony and PlayStation.
More details when we have them.
