I overall think we'll get the remaining SSBB characters except for Snake and the other two PT, which would add 12, and four more newcomers, being the three remaining Gematsu leak ones, and either a new DK, Metroid, or Zelda character. That would give us 49 characters, with five rows of 10, and the random slot.
