I think people's issues with Ryu in Smash speculation is similar to Terry: all this praise, admiration, attention, reminiscing, support, and discussion about the characters in the Smash scene came AFTER something connected to them happened (Terry's official reveal, Ryu in that fake leak). But go a month or two and further before those events and neither character was really discussed even remotely close to the same levels as the usual characters (Banjo-Kazooie, Geno, Shadow, Waluigi, Isaac, Dixie, etc). So it looks sudden and weird.
This would be like if Geno's first acknowledgement in Smash speculation was the Grinch Fake (so nothing beforehand, fanbase is comparably a nonexistent blip to other fanbases, Sakurai never mentioned him and there was no Mii costume). Then after that Fake Geno's in many discussions and seen as an obvious or expected or inevitable choice, but if you look at his full timeline im speculation, it looks like he came out of nowhere, almost like time literally skipping ahead. I think people are just confused at the sudden speculation for Ryu, where he is discussed so nonchalantly as if he was ALWAYS discussed to that level. He becomes an 'obvious choice' only until after something of any degree happens with him, but he wasn't dubbed obvious before that event.
And I don't want to knock Ryu or his fans. He's just the current example and this confusion can apply to other characters in speculation. Kind of like how Chorus Kids were barely, if at all, brought up to be added to Smash, but then Gematsu happens and out of the blue they are on everyone's prediction list, acting like they were always there from day one.
