I still have yet to see any evidence that points to there being more. No, Rosalina does not count. She was never planned for E3, and had she not been revealed during the December Direct, she would no doubt be part of leak 2. If the leaker had added her to leak 2 after her confimation, it would make the leak look false.
Thank you. Someone understands that the Gematsu characters are all good despite not being Cruel or Roidley or whoever's popular these days
Despite how bland he may seem, I have faith that Sakurai will do something interesting with Chrom. He exceeded my expectations with Pac-man, Mii, and Little Mac, so I'm confident Chrom won't be as generic as he seems on paper.
Also, the leak said "DLC" it did not say anything about characters specifically, so far all we know, it might just be stages. Gematsu + Rosalina could be it. Period.
tbh i don't want character dlc
Also, I hate to point this out, but the hyperlink in the OP looks bad. It stops at the "u" in "cut." Please fix.
