The console version of Super Street Fighter IV may be about to welcome fighters Yun and Yang and Evil Ryu.
Website EventHubs spotted their faces on icons for a new batch of Super Street Fighter IV Xbox 360 Achievements.
Alternative costumes for Yun and Yang were released on Friday, but these were linked only to the Japanese Arcade Edition of Super Street Fighter IV.
Last month, SSFIV producer Yoshinori Ono flew to the US to try and convince his colleagues to include Yun and Yang as downloadable extras. He also campaigned for the release of various game balancing patches.
Yun and Yang are twin brothers that were first introduced in Street Fighter III: New Generation.
Evil Ryu first appeared in Street Fighter Alpha 2.
