@ Cure Passion: That's what I used to think too, that the yellow cure is the 4th cure and the masked cure is is the supporter because 1) the yellow cure's outfit is similar to the rest, 2) the ending credits show Hummy on a yellow note pedestal.

But after looking at the Healing Chest, as PockyPrincess pointed out, the 4th colour suggests that the new Cure will be based off the colour purple, so I started to think that maybe the masked cure is the 4th member of the main team, and that yellow cure = princess of music = ako = the real cure muse (if those Japanese toy magazine scans are to be believed) is the 5th member that is more of a sub-member who has her own set of powers, sorta like Shiny Luminous.

Then again, all these are just my guesses. Let's wait and see what happens~ ;)
