There's been some confusion as to how many alternative costumes will be available to the old and new cast members in Super Street Fighter 4. In the new features trailer, it showed all characters having 3 selectable outfits, but later statements contradicted this.The current plan is for all returning characters to get a new costume, so they'll have a total of 3.
Characters new to Super Street Fighter IV are currently planned to have just 2 costumes, just like characters new to Street Fighter IV had.
