Verdict:
Ultimately, this release left us rather baffled. Aside from the increase in resolution, every other version of the game remains superior in various ways. While it's still Street Fighter 4 at its heart, the quality of the conversion simply isn't what fans of the series deserve. It may be quite playable for the casual players - but clearly it's designed to appeal to hardcore users still enjoying the title and looking for a console upgrade to at least bring it up to par with the PC release. All of the promotional material was focused on hyping this version as the definitive version and everything was in place for it to become the de facto edition for tournament use. It felt like Sony and Capcom really cared about the fighting game audience and were trying to do right by them with this all-encompassing release but the end results just feel sloppy.
It appears that both Sony and Capcom are actively looking into this situation, and we can only hope it will be just a matter of time before it is fixed. As a digital-only release, potential patches are less of an issue here than they would have been had this game been released on disc. The question we have is whether or not Other Ocean will actually fix the many and varied issues the game suffers from. After all, despite receiving patches, its release of the Mortal Kombat collection on PlayStation 3 remains a complete mess to this day (constant screen-tear on a 2D fighter? Really?). On the plus side, the raw basics do seem to be in place on USF4, and the game certainly seems fixable, with its steady frame-rate during gameplay standing as a solid foundation.
However, for the time being the game has been dropped from the Capcom Pro Tour - which includes both Evo and Community Effort Orlando 2015 - until further notice. While the game may be patched in the future it's going to be difficult to win back the trust of the fighting game community at this point. When a port of a seven-year-old game ships in such a state, aimed at such a dedicated fanbase, but comparing poorly to the PC and even the Xbox 360 releases, you have to wonder about the state of quality control in the industry these days.
