The update to Street Fighter IV that spilled out yesterday now has a name: it's going to be sold in a complete pack as Ultra Street Fighter IV, which adds five new fighters to the game, along with a range of tweaks.
Four the five fighters have been announced. They're Rolento, Poison, Hugo and Elena. You can find the details of the tweaks to existing characters here.
Ultra Street Fighter IV is the name given to a complete retail bundle including the main game and this new DLC. It'll cost $40. If you've already got Super Street Fighter IV, the new stuff will be available separately as DLC for $15.
From a splash screen grabbed by SRK, looks like it'll be available for at least the 360, PS3 and PC.
