This is what I'm referring to. Now for why this isn't realistic.
Super Mario: I agree that Bowser Jr.'s chances are good, but why would he put Geno above Toad and Paper Mario? Both are far, far, far more likely then Geno by a long shot and unlike Geno, are actually relevant and they are far more important to the Mario series then Geno is. Geno's chances are very low at best, I find it sad he thinks what he said is enough to make Geno have a good shot. He's also misinformed by the fact that Geno is a third-party character, NOT a Nintendo character.
The Legend of Zelda: None of his candidates have a good shot of getting into SSB4. Midna was a one-shot, Zant was a one-shot, and Ghirahim will probably be a one-shot. There are no likely Zelda reps left. Even Tingle and Toon Zelda/Toon Sheik, the two most likely Zelda candidates, don't have a good shot.
Donkey Kong: I can understand that King K. Rool and Dixie may have relevancy issue but I find it shocking that he would consider a third DK rep unlikely and yet thinks that Midna and Zant are more likely then those two, who clearly are more irrelevant then King K. Rool and Dixie in relevance, importance, and popularity.
His other argument for why he thinks King K. Rool will never be in SSB also sucks. If they've wanted to so much distance from Rare, why has King K. Rool continue to make appearances on Nintendo consoles and handhelds after Rare left? Nintendo has clearly made no serious effort to keep King K. Rool out of future DK games, if they did, King K. Rool would have never been on another Nintendo game after 2001.
Wario: I will never understand why people think a second Wario rep stands a good chance. Support for a Wario rep has died down after Brawl and I do not see many support for 9-Volt. Most of the supports left are going to Mona and Ashley and they barely exist outside of GameFAQs. DK will get a third rep before Wario gets another character in. I don't imagine us getting a second Wario rep until SSB5 and even then, maybe not at all. The only one that stands a chance of getting in SSB4 is Kat & Ana and it's not a large one.
Metroid: Definitely agree that Ridley will probably get in, although I think Metroid only needs two reps and that a third one is not needed.
Kid Icarus: I'll give him this as I see a third rep as a decent likelihood.
Retro: I agree with Takamaru, but he is the only likely rep for retro characters. I highly doubt we'll get a second retro rep this time around, two games is not enough to form a pattern. Mach Rider and Balloon Figher were dropped in Melee, which very much hinders their chances, especially since they lack move set potentials.
Pokemon: Why wasn't Victini considered? He is equally as likely as Zoroark and to dismiss Victini is silly, especially since Victini would also fit as an legendary. Genesect's chances are far from realistic as he probably won't be relevant enough for SSB4. If we get a legendary, it will be Victini. He's also forgetting the possibility of Lucario returning (It is NOT a given that he'll be replaced, remember that Mewtwo was planned for Brawl but was dropped due to time constraint) to keep his slot, Mewtwo returning, and a first gen Pokemon rep. I agree that Zoroark stands a good chance (Even if I'm against his inclusion), but the fact that he considered Genesect as a likely candidate and not Victini cause the argument to fall flat on his face.
F-zero: Samurai Goroh is more likely then Black Shadow since Samurai Goroh would be less likely to clone, has higher fan demands, and is more well known then Black Shadow, not to mention has appeared in the series from the start. The second rep will probably go to Samurai Goroh if we get one.
Star Fox: Star Fox is not nearly as big as Donkey Kong. I can see Krystal getting in, but she is in no way more likely then a third DK rep. King K. Rool and Dixie Kong are at least important to their series and somewhat relevant (They are also more popular choices for newcomers). By today's standards, Krystal may have high demands, but she has a hate fan base in Japan and that she suffers major relevancy issues. If Star Fox is big enough for four characters, then why not Metroid and DK, both of which are much bigger then Star Fox?
Fire Emblem: Black Knight and Micaich may have relevancy issues. I'm very surprised Caeda wasn't considered, since she's more relevant then either of these two.
Earthbound: Does not need three reps and will probably not get three. I'm shocked that he considers Claus more likely then a DK rep.
Other: Isaac has appeared in all three games and is a lot more demanded then Matthew. Isaac's chances are much stronger then Matthew's, who has only appeared in one game. Also, where's Saki and Starfy? Both have good chances of getting in, are more heavily demanded then Ray, and are at least somewhat relevant (Saki's appearance in Brawl as an Assist Trophy helps). If we get three new non-retro franchises, it'll probably be Little Mac, Isaac, and one of Saki and Starfy.
3rd Party: Slime is more then just a generic enemy. As he said, Slime is the mascot of Dragon Quest. Slime has also had three games to a spin-off in the Rocket Slime series (The latter of which will be on the 3DS), and unlike Mega Man, Travis Touchdown, or Ryu Hayabusa, has appeared in cross-over games. Granted his chances are that great, but let's be honest here, it beats out Travis Touchdown's chances, who isn't really even iconic yet (His only chance is that Suda 51 wants him in). The only one that has a good chance is Mega Man and I find it utterly ridiculous that he thinks Travis Touchdown will probably get in.
Summary: This list fails to be realistic. He puts in characters that suffers from major relevancy issues like Black Shadow and Midna in yet doubts the possibility of King K. Rool and Dixie Kong getting in, even thought what relevancy issues they have are minor at worst. Geno is third-party, not a Mario character. He also puts undeserving characters like 9-Volt and Zant in but ones that are more deserving to be in SSB4 like King K. Rool, Starfy, Saki, and Isaac are not really considered. Also, his argument for Travis Touchdown being the most likely third-party rep is not strong enough and is unconvincing.
