Capcom announced Ultra Street Fighter 4 during Evo 2013. Billed as a major new update for Super Street Fighter 4 Arcade Edition, the update will introduce five new characters, six new stages and new modes and features.
Four of the five new characters have been confirmed as: Rolento, Poison, Hugo and Elena (pictured below). The fifth character, who has "never been in a Street Fighter game before", remains unannounced. The six new stages include Pitstop 109, Mad Gear Hideout, Cosmic Elevator, Blast Furnace, Half Pipe, and Jurassic Era Research Facility.
Ono also recently said he's not currently working on a new Street Fighter game for Xbox One and PS4 as he doesn't currently have the research and development budget or the staff.
