Capcom has come out with updated release info for Ultra Street Fighter IV and there are a few different dates to keep track of across the multiple versions.
Up first is the $14.99 digital upgrade for Xbox 360 and PS3, out in early June. The same upgrade is coming to PC in August, and that's also when the 360 and PS3 full digital bundles and retail releases are hitting. These are $39.99 and include all of the costumes to date.
Given the late PC version, the full digital bundle on that platform will be slightly cheaper at $29.99 when it's available in August. According to Capcom, this schedule "was the only way that we could ensure USFIV would be included in the largest fighting game tournament in the world."
In addition to location tests for Ultra Street Fighter IV, it will be playable at Capcom Cup on December 14, 2013 at the Hyatt SFO. Follow the link below for specifics.
