(SOURCE)
Here's the story.
About a week ago, respectable NeoGAF member Sal Romano, who runs a site called Gematsu, received an email from a source claiming that Villager, Mega Man, Wii Fitness Trainer, Little Mac, Pac-Man, and Mii would be revealed at E3. Sal did not post this on his site because he wasn't able to verify the information, but he did jokingly post the list a day before SSB4's reveal on NeoGAF as a "prediction" just in case it was correct.

Look at the date. It's important to note that the post hasn't been edited at all.
Sal told me that as soon as Wii Fit Trainer was revealed, he ran and posted the list on his site because he knew at that point it couldn't have been a lucky guess from his source.

I received some additional verification that I'm not going to post, but that's the gist of it all. Sal's legit and his source is credible. It's only a matter of whether Nintendo decided at the last minute to change their E3 plans and hold off on Little Mac, Pac-Man, and Mii.
I wouldn't mind these characters, at all.
