How did I miss this thread all day, whatt?? I'm gonna repost something I posted elsewhere given the relevance of the Gematsu assumption.
We need to look at the assumptions we are making here.
One, that Gematsu is correct. Yes, a lot of it is. Okay, concede. Likely so, but it is still an assumption.
Two, that it is all the characters. Rosalina disproves this, and to me it shows that she either was added later to development, or that she was initially going to be secret, and later switched to not be a secret character (thusly leaked). Which brings me to point three-
Gematsu is all the characters we will get. Why? What point does that serve to reveal all of the characters? Judging by who we have seen revealed, it seems to be the characters who would generate most hype in the non-smash fans; that is, not characters particularly wanted by fans already established in the game, but by outside sources. Variation. It would make complete sense for the locked characters to be the ones we have wanted to be in the entire time, the ones previous with some connection to smash in some way (as a boss, trophy, AT, etc). It would serve Sakurai little to blatantly ignore all of these characters.
Honestly I cannot fathom the Gemtatsu leak being anything but the characters who would be revealed before the game. We all seem to even glaze over the rosalina bit, but either she was added later, not included on the leak intentionally (potentially along with others), or was originally not going to be revealed and then later was (likely because she was switched onto the starting roster-- perhaps the reverse happened with Ike and chrom, where Ike was going to be secret and chrom starting roster, but after the leak, they were switched). We have more evidence pointing TOWARDS more characters from the leak than not.
Now-- if the leak is not what is disappointing people, what is?
We were given information about a new character reveal. It will be a big deal. We were told specifically that we are near the end of new character videos, which we knew- the game is coming out soon. That almost sounds specifically like we should in fact expect more characters to be in the game, or else he would have surely said 'there are not more new characters,' because if it were all the newcomers, he would have told us. THAT is terrible marketing, pretending to possibly have more newcomers when you do not have anymore. If all the newcomers are somehow revealed before game launch, the point would be because everyone would find out and he wants us to know.
Guys, we have more characters. I honestly think it will be Shulk, but if not, my money is on Ridley.
