 Earlier on before the beta testing, Capcom announced that main  Street Fighter characters Ken Masters and Ryu Hoshi would not be in  the third installment of the series and that Sean (Kens student),  would be the main Hadou character. This choice, however, was changed  after fans complained that the game would not be good if the  original characters would not be in the game. So Capcom ended up  putting them in the game and Sean as just a student of Ken (and it  also really made Ken and Ryu the only main characters to be in all  the Street Fighter games).
