Here we go:
Apparently top choices were Inklings, Snake and Ice Climbers if I read that right.
Followed by Sora, K. Rool, Naruhodo aka Phoenix Wright, Bomberman, Chrom, Bayonetta, Ridley, and among the franchises Pokemon, Dragon Quest and FF were quite strong.
Then the following were mentioned after them as loose but remarkable after the top ones:
FE (combined), Tales (Combined), Bandanna Waddle Dee, Monster Hunter, Paper Mario, Forest? (I think Animal Crossing), Castlevania (Combined), Dixie, Megaman (Combined?), Magolor, Professor Layton, Sonic (Combined?), Dante, Tohou (combined?), Master Chief, Kid Icarus (combined), Ashley,
Crash Bandicoot, Fate Character, Waluigi, Street Fighter (combined?), Minecraft, Fiora, Shovel Knight, Dry Bowser, Yo-Kai Watch (Combined), Ryu Hayabusa, Rhythm Heaven, Banjo, Okami, Krystal, Impa, Bio (combined) (Assuming RE), Rayman, Robin (Isaac?), Chibi Robo, Daisy, Kat from Gravity Rush, Mother series (combined), Puyo Puyo, Midna, Oliver (? I think Ni no Kuni was mentioned by the leaker), Geno, Mai Shiranui, Takamaru, Sakuraba Neku, Wonder Red, Starfy, Metroid (combined), Petey Pirahna, Tekken, Skull Kid, Custom Robo, Spyro, Culdcept
Mario, Kirby, Zelda and Pokemon combined is big. American heroes and anime characters were also popular.
