Even though Street Fighter x Tekken’s free 2013 update was slated for a January 19th release on PS3 and X360, Yoshinori Ono has unveiled on SF25th Global Tournament Series Grand Finals that the update will be delayed to January 29th. Yoshinori Ono did not reveal the reasons behind this slight delay, and unfortunately we do not have any news for when this update will hit the PC, though we can safely assume that it will come two-three months after the console release. You can view below a new trailer that showcases some of the changes of this new update.
