Maybe so what do you guys think about the gematsu leak a lot of people say its been proven wrong but the way I'm looking at it it actually hasn't been proven wrong yet
The person feeding information to Sal Romano had information, but it was quite outdated. I don't think anyone is going to argue that someone can just
guess characters like
Wii Fit Trainer alongside "Animal Crossing guy" (a series that Sakurai himself said wouldn't fit well enough with the Smash universe, and in the end have at
worst 7 of 11 characters right. It was found out that the Mii Fighters information found in his 3rd wave of information was accessible by anyone on Nintendo's E3 site if you guessed a fairly-predictable admin password. If we look at the 4 disputed characters of the list. Also, just to say now, the tipper never said he knew ALL the newcomers.
"Pokemon from X/Y" - Sakurai himself said early listings for the roster had an open slot for Pokemon X/Y even though the games were in production, because he wanted to represent the games somehow. Based upon concept art, he chose Greninja (presumably before a name was even made, or even before the final design was made) because he thought it looked cool and people would end up liking it. Going with the theory that he has outdated information, this lines up.
Chrom->Lucina&Robin - Sakurai wanted to include Chrom as a representative Awakening because it is the most recent, and best selling, Fire Emblem game (whose sales saved the franchise for titles being released after SMT x FE). However, when playing through the game, he really didn't see much that he could do uniquely with Chrom. Robin, on the otherhand, seemed like a much better pool for a creative and unique character. Lucina, as Sakurai has stated many times, was planned to be a Marth alt but in late production was turned into a Clone character with some fair work added in (presumably to help fill the slot of a character ultimately cut due to time constraints). Once again, presumably outdated information.
Shulk - Protagonist of one of the most critically aclaimed Wii titles, second-party, and after all the work done to get the game westernized, has a place in Nintendo's history (being able to do what Mother 3 fans couldn't). Before Gematsu, he was IMO one of the most deserving newcomers for what his game is in Nintendo's history.
Chorus Kids->Marshal? - Rhythm Heaven has been a small franchise for Nintendo (3 games, 2 released internationally). However, it is a very fun, quirky, and creative series made by the studios who make the Warioware games. Between the Sneaky Spirit in Smash Run (one of 2 enemies we don't have a confirmed playable character tied to, the other being the Ice Climbers' Polar Bear) and the fact that Wario himself has yet to be revealed... it's theorized that the two will be revealed together. I, to a degree, throw Warioware and Rhythm Heaven together due to how strong the two have ties together. I believe that Sakurai could easilly see potential in this series to have a Game & Watch-style weird little character with a moveset based on the collection of Mini-games and the "gimmick" of perhaps a rhythm-strengthened moveset. (I'm awaiting permission to post my moveset on the Marshal thread to show my point). The question is more of: If Sakurai wanted a R.H. rep, was it Chorus Kids? And due to some of the problem Rosalina & Luma akin to the Ice Climbers gave the 3DS, was a trio too intensive and thus downsized to Marshal?
TL;DR: He had outdated information, and only one character has been proven not in the final release as playable. We don't have much reason to not expect Shulk or a Rhythm Heaven character as 2 (of what I predict to be in a total of 4 more) newcomers.
