Over-powered characters will be re-balanced for free.
At yesterday's EVO 2011 Fighting Tournament, Capcom announced that a patch for Super Street Fighter IV Arcade Edition is currently in the works.
Super Street Fighter IV Arcade Edition Ver.2012 will address the balancing issues many players had with the game, and will be released at no extra cost.
Series creator Yoshinori Ono didn't reveal any concrete details, but many fans will expect to see the massively over-powered Yun and Yang get some notable changes.
Capcom USA plans to have the update out "in the fall or winter time", and - to reiterate - the update is free.
