Yeah, I'm somewhat aware. I remember lurking and reading a few posts about the subject and Capcom's mistake of not releasing PS1 ports a few days/weeks ago. I would think that almost all the fighters ported to PS1 suffered in one way or another graphically, but the console crowd at the time only cared about having a playable highly popular piece of software in their living room. Capcom missed the boat big time on that crowd and the same posts mentioning the terrible DC sales also claimed that Capcom's decision was correct and based on accurate data. To that all I can say is that we know of Capcom's "Capgod", "Crapcom", and "Capcpom" moments/eras. Companies can make terrible mistakes even with all the data in the world. I think aside from changing the roster too much, Capcom made the huge mistake of not throwing full support behind their main entry in a numbered Street Fighter title. The result was a good decade long hiatus. The same could happen just as easily to SFV if Capcom doesn't see stellar sales and their executives lose interest. It wouldn't be the fault of SF2 saturation, weak sales, no Xbone port or no arcade port. It'd be the result of several factors blending together.
TBF this post is quite a bit more detailed than my initial one that was focused exclusively on the arcades. Capcom nut putting their full support into 3S kinda just hit me now (In that "Eureka" moment way, not the drooling fanboy way), so the keystrokes just kept pouring out.
