What we have thought to be a single character reveal for Super Street Fighter IV turned out to be an announcement of three characters. A leaked image of a page from Famitsu revealed that Adon will be heading to Super Street Fighter IV along with two Final Fight characters, Cody and Guy, who have appeared in the Street Fighter series in the past.
The scan also teases another character. The scan shows Guy punching a kunai out of the air while the text besides it asks whose kunai Guy must be punching. Some are speculating that this is related to the character Ibuki from Street Fighter III.
Other then that there aren’t any translated details from the scans as of yet, so if you need to know more you will just need to sit tight till some translated info pops up. In the mean time you can look at these beautifully blurry scans.
