Smash Poll Early Results:
Japan:
1st: Inkling Girl/Boy (are you serious? The very few Wii U references we've seen are stages and OSTs, but no characters, meaning that, if all goes the same way than Brawl or Melee, they will possibly be added in the next Smash game)
2nd: Krystal (OH YEAH!)
3rd: Wolf (returning veterans? Nice.)
4th: Isaac (... He should have gotten the Little Mac treatment, which is "getting into the base game as playable after being an AT in the previous game", to begin with, so he's quite unlikely as a DLC)
5th: Keita Amano (... Who is this I don't even...)
6th: Masked Man (Another Mother rep? ... If anything, Mother should be getting a stage with Porky as a stage boss on it)
7th: Ice Climbers (3DS problems, so no)
8th: Ivysaur (returning veterans? Nice... again. But I'm surprised he got over Squirtle)
9th: Wonder-Red (See "Inkling Girl/Boy" for counterargument)
10th: Viridi (WOULD BE JUST PLAIN PERFECT FOR ME!)
11th: Snake (I WANT HIM BACK! HE WAS MY BRAWL MAIN! ... But I know he's not that likely either way)
12th: King K. Rool (are you friggin' kidding me?! ANOTHER DK REP?! ... Dear god, no)
13th: Midna (one-shot appearance, also already an AT so maybe in the next Smash, but not as DLC for this Smash)
14th: Ryu (If we get three reps per third-party company, we'll have Mega Man, Phoenix Wright and Ryu to represent Capcom)
15th: Amaterasu (possible, but that likely. Also, less important Capcom third-party than Ryu or Phoenix Wright)
16th: Squirtle (I WANT HIM BACK WITH THE OTHER WATER STARTERS AS ALTS!)
17th: Impa (one-shot appearance, also not the highest priority for LoZ characters, since we've got all the representative figures of the series already: Link, Zelda, Ganondorf, Sheik for playstyle reasons, and Toon Link for "clash of looks")
18th: Toon Zelda (higher priority than Impa, because she's an important character in the same style than Toon Link)
19th: Pichu (for the sake of "avoid alienating Melee fans", he's almost a shoo-in with Roy)
20th: Bayonetta (see both Wonder-Red and Inkling Girl/Boy for counterargument, also less kid-friendly than even Snake)
Americas:
1st: King K. Rool (They don't know when to give up, don't they?)
2nd: Snake (See "Japan" mention of him)
3rd: Wolf (I'm all for returning veterans)
4th: Paper Mario (I don't think someone who don't know the series would want to buy a third Mario, since there's already Mario and Dr Mario in the base game)
5th: Ridley (what the hell, are you serious.
He's even less of a shoo-in than even Nabbit, because he got officialy and directly deconfirmed)
6th: Isaac (See "Japan" mention of him)
7th: Tails (Miles Tails Prower would be a nice addition, now that SEGA belongs to Nintendo. However, if Smash doesn't consider SEGA a new part of Nintendo, Tails would be impossible, even if we get three reps per third-party company)
8th: Shadow (even less of a shoo-in than Tails, but for the same reasons and also because he's an AT)
9th: Young Link (as much as I want all the veterans to be back, Young Link would be better off as a Toon Link alt, since they have similar stats and attacks)
10th: Shovel Knight (ARE YOU SERIOUS?!
)
11th: Pichu (see "Japan" mention of him)
12th: Ghirahim (same than Impa)
13th: Chrom (part of a Final Smash, and irreplaceable because even the Palutena's Guidances mentions him as a part of said Final Smash)
14th: Krystal (see "Japan" mention of her)
15th: Quote (A PC character? Nope.)
16th: Simon Belmont (If we get another Konami rep, Snake is more likely to come back)
17th: Ryu (see "Japan" mention of him)
18th: Shantae (Like Bayonetta, she's mostly a character for perverts. Also, not the most kid-friendly character either)
19th: Chorus Men (Rhythm Heaven didn't even get musical representation in Smash, and mostly doesn't have a planned sequel for now)
20th: Phoenix Wright (He and Ryu would be perfect to represent the two other eras of Capcom, which are "brand new" and "ever-lasting" respectively, since Mega Man has the "old-school" era covered)
