Relevant information paraphrased:
Cyrus (Cavalier) - both verisons
Elfie (Female Knight) - Nohr
Harold (Gaston/Fighter) - Nohr
Hinata (Myrmidon) - Hoshido
Oboro (Lance Fighter) - Hoshido
Rinka (Oni) - Hoshido
Tsukuyomi (Red Hair) - Hoshido
Felicia can reclass(promote?) to a Brave Hero, a Bow Knight and a Strategist
Multiple promotion options seem more likely.
EDIT
Report on the main site EDIT2:
Digital issue is now out. Only new piece of info I can find is that Harold can promote from a Fighter(?) to a Berserker.
