Street Fighter 5 has been potentially confirmed as a PS4 and PC exclusive game after a short trailer for the game was accidentally set live on YouTube by Capcom.
According to NeoGaf the trailer -- a short inspirational affair extolling the game's fans and history -- appeared for a brief time on Capcom's YouTube channel before being quickly taken down.
Street Fighter 4 first appeared in 2008, Capcom has since chosen to keep the game in service, instead offering numerous versions and DLC updates over the years.
Now it's important to note that simply saying the phrase 'exclusive' doesn't actually mean it won't arrive on Xbox One. Considering the limited information we have it's still plausible that this simply means it's a timed-exclusive - arriving on Xbox one at a later date.
