Look at the roster and look at what Sakurai says about Alternate Costumes.
“With the Wii Fit Trainers, the male and female Robins, the Villagers, and Little Mac, varying their appearances and voices works just like selecting alternate color variations. However, whenever there is even a small difference in abilities, that character gets an actual roster slot. That is why you can select Lucina individually.”

Do the Wii Fit Trainers and Animal crossing characters make any vocal noises? I'm sure the Robins do.
It just seems that there are more Alternate Costumes that will have different voices and perhaps name besides those listed. He seems to need to contrast it more with Lucina's special status. It just seems like he didn't have enough revealed examples to truly express the difference.
I can see based off the leak roster there also being:
1. Earthbound Rep: Ness/Lucas
2. Sonic/Metal Sonic
3. Alph/Olimar
4. Protoman/Megaman
5. Fox/Wolf
6.Meta Knight/ Galacta Knight
And based off the leak, Sakurai decided that Dr. Mario, Lucina, and Dark Pit were the ones worthy enough to just make with stat differences.
WFT's not worthy, just gender.
Robins, same story
AC, same story
Ness/Lucas, can easily make an earthbound character with a combined moveset of Ness +Lucas, especially with customizable moves.
Sonics, not gonna add another 3rd party, so just keep it an alt
Megaman, same as sonic, protoman would be another 3rd party
Startfox, similiar to earthbound situation.
Meta Knight, Galacta knight not nearly popular enough to be a clone, but could be new alt.
Doing this would keep a couple of the cuts and explain what Sakurai really is talking about with "Special Lucky Alternates who made it to clone status." And that there are actually quite a bit of alternates with different voices and names, etc.
