I imagine no changes from the Wii U/3DS roster and we'll see the DLC characters too.
As for new additions:
Ice Climbers (hopefully enough processing power to include 16 Popo & Nanas)
Inkling (Nintendo IP Splatoon)
Cross (Nintendo IP Xenoblade X)
Wonder-Red (Nintendo IP Wonderful 101)
Takamaru (Nintendo IP Murasame Castle)
Shovel Knight (Third Party Yacht Club Games)
Jibanyan (Third Party Level 5 Yo-kai Watch)
Lloyd Irving (Third Party Namco Tales of Symphonia)
Dragon Quest Hero with 9 Skins for each game (Third Party Square-Enix)
Total: 76
And in 50 posts as of writing this, precisely one follows the rules in the OP. People, reading is not that hard:
6. Please post total amount of characters at the bottom or top of the post, so it would make it easier for me to do the scores. Please make sure that your total count would included transformation characters as well.
