There is a reason why all the SSF2 characters except for DeeJay and T. Hawk ended up in vanilla SF4 and why most of the revealed veterans so far for SF5 are SF2 characters. SF2 characters are the characters that are among those SF characters that gets the most merchandise and
references in pop culture. When in comes to the general gaming population, mention the franchise and SF2/SF4 are the only games that gets recognized, with the latter game incorporating the Original 12, Akuma and Cammy.
I suspect bitter fanboys angry at the supposedly "undeserving" attention SF2 is getting is what let some people to write something as delusional as that, grossly overestimating the popularity of their favourite niche character whilst treating legitimately iconic characters as nobodies (Even I as someone who wasn't a big fan of the Miis getting into Smash recognized how logical their includion would be, considering how big of a Nintendo icon they are)
