multiple fan sites, it contains confirmation that three new characters (well, old ones, technically) have joined the already bursting roster of Super Street Fighter IV. Newly added Ibuki, Makoto and Dudley all hail from Street Fighter III (the trio being a ninja, a karate master and a boxer, respectively). The news has the SF community crackling with excitement; even Udon Entertainment, creator of comic books based on the famous fighting series, has caught the "Here comes a new challenger!" fever.
