Round 1, pre-E3 2013, guy leaks to Sal Romano, owner of Gematsu that Villager, Megaman, Wii Fit Trainer, Little Mac, Pac-man, and Mii will be in.
Round 2, pre-Smash Direct, guy leaks to him again, claims Pac-man and Mii are still coming, but also says Palutena, a Pokemon from Pokemon X and Y, Chrom, Shulk, and Chorus Men are coming as well.
Round 3, pre-E3 2014, makes the same claims again. Also corrects Mii to being Mii Fighter, mentions that they're considering cutting Lucas or Ness, and leaning more towards cutting Lucas, mentions this will be the last E3 before Smash 4, and mentions that they're planning on character DLC, and that he's a bit bummed about it.
Chorus men.. wait-- really? That's.. odd.
Weird about the Lucas/Ness discussion tho. One of them was basically a clone of the other so I don't really care.
As for DLC... well, as long as it's free or not that expensive sounds good to me.
Thanks for the info.
