Capcom's Yoshinori Ono spoke with Videogamer recently about the upcoming Street Fighter IV title. He discussed several features of the game, including the lag during online play being a "huge problem," and the decision to remove parrying from this offering. He also mentioned that once better infrastructure is in place, online play "will definitely be the future of the fighting game."
