Here's some quotes from the article:
"A Nintendo Direct feed is coming on January 31st, the anniversary of Brawl‘s JP release"
"Little Mac and Takamaru were two of the first newcomers chosen, representing the East and the West."
"K. Rool will be playable, featuring a redesign of the character put forth by Retro Studios. (Could a new Donkey Kong Country be on the way?)"
"Ridley will be playable, featuring his “evolution” from Other M. He and K. Rool were chosen due to high demand."
", Ghirahim, and Dillon are planned to be included in the roster, but these decisions are not finalized"
"Platinum Games wants to include a character, but no decisions have been made yet. Characters from The Wonderful 101 look more likely than Bayonetta."
"A new Yoshi character to be introduced will be playable, likely to originate from Yoshi Land Wii U."
"Starship Mario, Pushmo Park, Cookie Country (Kirby), and Giant Chasm (BW2) will all be featured stages."
This sounds so cool.
