Ryota Niitsuma, assistant producer on the arcade version of the game, told Videogamer that the two fighters are a little too powerful. When asked if any SFIV characters were disproportionately powerful, he replied, "Well first of all I might have to apologise! Does he involve being slightly blinded and scarred [laughs]?"
While he admitted that "Yes, Seth and perhaps Sagat might have turned out a little bit stronger than we expected," Niitsuma said that skilled players of other World Warriors can still beat Sagat or Seth players. And yes, we know that the image doesn't have anything to do with Sagat or Seth, but we wanted to link to Capcom's recent gallery of SFIV wallpapers, and it doesn't feature any images of those two characters.
