I think there may be 5 Cures, 4 main ones and 1 special one. The 4 main ones will be Melody (pink, transforms with Dory), Rhythm (white, transforms with Rery), Beat (blue, transforms with Lary) and the masked Cure whose real name is not Muse (purple, transforms with Dodory).

The special one will be the yellow Cure, whom I believe is the real Muse, and that her transformation partner is the Crescendo Tone (yellow = gold?? lol) Some Japanese websites state that Cure Muse will "appear" in episode 35 (yes, "appear", not "be revealed", so Muse is definitely not the masked Cure), and since that episode's title is "Kirakira! That girl is the princess of music-nya!", I'm thinking that it'll be fitting for the princess of music to have the Crescendo Tone as a partner, right? ;)

As of now, the only thing I can't explain with this theory is why the masked Cure hides her identity and pretends to be Muse. Who knows, maybe when she reveals herself finally, she may also reveal her real identity (anyone still up for Cure Symphony or Cure Tempo??)
