Count me in with the folks that think that Capcom should go back on their word and release a Super version. Yet another PR shitstorm would result, but it's probably the best move to make at this point. The current release is toxic and I see no reason to continue pouring resources into it.
People were pissed with super sf4 because it rendered the old version useless and separated the online community for SFV they can just do it with a rerelease of the game with more modes new characters stages..etc and offer this stuff as dlc for the people who bought it early since system balancing is being done for free in SFV.
