This morning a Capcom video briefly popped up online confirming Street Fighter 5 and that it would be a PlayStation 4 and Windows PC exclusive, according to a NeoGaf thread.
The video, which has since been removed, talks about "rising up" and breaking through your ceiling. It concludes with a shot of the logo for the game and the words "exclusively on PS4 and PC." It also includes a link to what appears to be the future landing page for the new game, though the page isn't live yet.
Of course the word "exclusive" has so many different meanings in the video game industry that it's hard to tell if this game will never show up on an Xbox platform, or if it will just show up there later.
It appears the video was set live accidentally a bit early. This weekend two events promise to have a number of new trailers, news and game reveals. The first ever Game Awards kick off tonight in Las Vegas and the PlayStation Experience officially starts on Saturday. Street Fighter executive producer Yoshinori Ono tweeted early this morning that he had just arrived in Las Vegas for the PlayStation Experience.
We've reached out to Capcom for more details on the game and will update this story when they reply. While Capcom hasn't commented on the leak officially, Katsuhiro Harada, game director of Tekken, seemed to react to the link with this tweet. (Though he later said — perhaps as a joke — that it was a reaction to a July leak of Tekken info.)
