Ultra Street Fighter IV would be coming in August, both as a $14.99 USD upgrade and as a full game for $29.99 used.
According to the post, "Next up is the release date information for Ultra Street Fighter IV. Right now, we are hard at work to bring the game to all of our fans as soon as possible, and want to ensure there is enough time that players can practice to compete at Evolution 2014. As such, the digital upgrade will be available in early June for $14.99 (€14.99) on PS3 and Xbox 360. Following shortly after in August, is the digital upgrade for PC at $14.99 (€14.99), as well as the PS3 and Xbox360 full digital bundle and retail versions, which include all previously-released costumes for $39.99 (€39.99). Since our PC fans have to wait longer for the content, we have a special deal where they can get the full digital bundle including all of the previously-released costumes for only $29.99 (€29.99), also in August. Apologies to our PC fans, as we did want to release simultaneously, but this was the only way that we could ensure that Ultra Street Fighter IV would be included in the largest fighting game tournament in the world.
Additional announcements for Ultra Street Fighter IV will be at 12noon PST on the 14th December during the Capcom Cup, which will feature such games as Street Fighter X Tekken, Ultimate Marvel vs. Capcom 3 and Super Street Fighter IV AE: 2012 in tournament play.
